I understand that this bothers you significantly, but you lost me at "real world logistics". We're talking about a show in which we just saw a gigantic, telepathic gorilla fight a man who can run at supersonic speed and travel through time. If one of the most bothersome and unrealistic aspects of the show for you is that we haven't explicitly seen those prisoners get fed, the main inconsistency might fall on your mindset when viewing the show.
As for providing for the metahuman prisoners being no small feat, what makes you say that? You've seen all that the Star Labs people are capable of and all of the technology that is at their fingertips -- including modification of the particle accelerator chamber into an advanced prison for metahumans, with "prison" cells that they can mechanically move around like the parts of a rubix cube. Do you think it would honestly be difficult for them to have developed an efficient way to drop 3 meals a day into their chambers without ever having to enter the cells themselves? Or to connect the prisoners' cubes to a shower cube when needed? They could have had an automated feeding system, for all we know, tailored to the needs and physiology of each prisoner.
Point being, there are more important things this TV can and should be utilizing screen-time for. Comic books don't often dwell on logistical factoids like this one, so I don't see why it would be a huge negative that this show (which is essentially like a live action, weekly comic book) doesn't dwell on it either.
But really, I am sorry that this irked you in the way that it did -- no sarcasm or snark intended. There's so much to love about this show, and I feel bad that something like this hindered your overall enjoyment of it.
Well, it does bother me because like I said, it reeks of "playing with my action figures" type writing and not making it about characters that, no matter the bending or breaking of physics that is required for a superhero show to work at all, there still has to be a weight to the people and the circumstances and details like "How are they exactly caring for these people" (which is linked to the question of the morality of doing this in the first place too) is indeed, part and parcel of separating strong writing, for myself, and mediocre storytelling.
What do I mean by "playing with my action figures"? Well, I was a kid that played with lots of action figures and of course had a play set or two to have adventures in, like lots of us. Now inevitably in these play sets, especially the ones that serve as the back drop to the hero characters, they have some "jail" or lock up or cell to put the bad guys in. As a child (say between 6 and 12), did any of us really think about anything beyond the "good guys" win and put the bad guy in the jail in the play set? No. I hazard that 95% us did not. But... We were children. We had expectations and yes to go against the trope, even the "limited" imaginations of children. As you get older, the questions such as the one I posed not only seem germane, and kind of silly that there isn't at least SOME kind of answer (seriously... I am not asking for a multi-episode arc of Cisco feeding and bathing metas... A couple of lines about how they are pulling this off, is better than hand waving away implications or not bringing up what would be a huge logistical nightmare for Barry and the gang, powers or high tech solutions notwithstanding) but you start to realize there are story and character potential that is wasted if you don't put some thought into this stuff as well. It also, frankly makes for simply sloppy writing. As a for instance... In comics or in animation have you ever noticed that in "super villain" prisons that A. Too often the villains are in their cells WITH their costumes on? Or, B. That the villains' super powered sundries (WEAPONS, ect.) are stored ON SITE AT THE PRISON? Would either of those things have bothered any of us at the age of 10? No. But... We all ain't ten years old anymore. This isn't about "suspension of disbelief" or needing everything explained... It's about competent storytelling, and not treating us, the audience, like small children. It's about, in spite of the fantasy concept (world with super powered heroes and villains) not using it as an excuse for shoddy world building. "Oh, well, it's a show where a guy in a silly costume with super speed fights other guys in silly costumes... We don't have to go all that deep into anything."
This extends to other areas of the show, and yeah, consistency is an issue the show has, especially with Barry's supposed power levels and even characterization. He's supposed to be the science buff and a professional crime scene investigator, and... He's actually supposed to be quite good at it. Now, that is a job that requires precision and focus... But we had to apparently have Barry learn these things from Ollie Queen? He has super speed now, was always a science buff (from child hood), but he NEEDS to phone home to STAR to continually get advice or get some equation or science info? These are issues on the show that I doubt I or other fans haven't thought could use some improvements. This last episode in removing the Pipeline prisoners was a very good step, as it relieved the show of this ridiculous idea that Cisco and Caitlyn and Wells and Barry were doing everything we were seeing every week AND other work, AND also take care of the prisoners. World of super speedsters or not, NOT addressing such things smacks of just not caring. "It's just a show about a comic book character... We don't need to think about that."
Take a look at DareDevil... The truth is that today's Hell's Kitchen and NYC in general is NOT the NYC of Miller's era of DD. Realistically you couldn't do that version of DD today, cuz frankly, Hell's Kitchen is actually quite a Tony place to live these days... But the writers managed to think things through and pulled it off. "Hmm... Oh, right... the attack in AVENGERS by aliens would change things in the city, there might be areas that would become more high crime... OH... And with all the destruction we'd have all this construction going on and contracting and where you have that, you have unions, you have kickbacks, you have organized crime... TA-DA... A crime filled modern NYC as the back drop for DD." That's taking a fantasy concept, applying real world ideas (while still keeping it firmly entrenched in a universe where there are Helicarriers, green rage monsters and people with "radar senses" that were trained by secret martial arts cabals) and having it pay off handsomely. This isn't also a question of "tone" or "maturity". That same sense of "we aren't just going to hand wave stuff or take tropes and ideas for granted" could and should be applied to any and all sorts of fantasy concepts to make them just all around better product. Take the INCREDIBLES as an example... Now, was it at the end of the day, and all ages family entertainment? Yes. Was it a well defined and well thought out world for telling super hero stories? Yes. Those things do not need to be at odds and I feel that fans that want that aren't just being nitpickers or are over thinking things, most especially in live action adaptations aimed at an audience over the age of 18.
Again... I don't want to have a deep, philosophical treatise on the incarceration of meta humans... But it helps to give a show like this dimensions and depth when the writers at least DO give a damn about those types of details to care enough to at least address such things in a somewhat logical manner.
This may sound like I "hate" on the show. I do not. I very much like Gustin, think he's doing a good job. His scenes with most of the cast, especially with Joe or his father are actually quite good drama wise. The SFX is killer on the show, the writing of the Wells "mystery" has been compelling as hell and while I have my quibbles, the evolution of the Flash as a super hero is a great way to get a handle on such a powerful character for TV. I mean... He can't just start out vibrating his molecules and creating tornado gusts with his hands. That has to be learned. The problems with the show for me are some spectacularly bad casting decisions for what should be key characters, or worse unnecessary characters, as well as some spotty writing on a handful of other issues on the show. But... I am still watching every week. The show is enjoyable. If I didn't like it I would have dropped it the way I did SHIELD, despite hanging in until just about the end of season one of that show. I don't see that happening with Flash... I just wish that they put some more thought into certain issues on the show as well as get that the "CW" stuff, is not what makes that or ARROW, hit shows. It's the high concept super hero stuff. No one (colloquially used) is tuning in for the Barry/Iris/Eddie stuff. Why? We could get that on ANY OTHER SHOW on the CW. It's obvious that the super hero aspect is what is selling the show and putting it on the top ratings wise.
