No more 'uncreative' than mutancy as an origin,
Which works for the X-Men because they're mutants....so it would make sense there'd be evil ones.
or having all the villains be insane in Batman's case.
Aren't all villains insane? At varying degrees, more or less?
It keeps things together. It never gets boring. Having their own backstory doesn't change.
It does get boring, they all come from one place, there's no mystery to it if they all get their powers from the same source, not to mention lazy writing. Cool for Static and X-Men because of their origins and the context of their stories, not for Flash, batman, Spider-Man, etc.
How they got in contact with this tech and who they were before that still needs to be explored in each case. When you do it another way, and you constantly have a new macguffin for every villain every week, you have to get rid of it and explain why this person is the only person who will ever have/use this technology.
So you have to be a little creative? What's wrong with that? In a fantastic sci fi world, there should be multiple ways for villains and powers to come about. It'd be like making Green Lantern's villains all get their powers from the same place Hal got his or have all Superman's villains be from Krypton. And say what you will about them, but I like many of Superman's rogues gallery.
Or you have to make every villain, regardless of their skills or temperament an inventor/technician/engineer to explain why they alone have created this device.
No you don't. They can always steal it or get powers in some way too....I really don't see what the problem is.
It's messy, you have a lot of things to clean up. It's not tidy.
Dude....get over it.

You can be creative enough for it all to work fine (well maybe
you can't, but the possibility exists for it to not be anyway near as banal as you're projecting).
It's unnatural for 20 pieces of society-redefining technology to appear within a year and have no major effect on society. That's bad writing.
Sooo....it makes sense for 20 pieces of society-redefining technology to appear within a year as long as it comes from the same place, right?

This is a story about a guy who does pretty unnatural things from an unnatural lightning and chemical accident in an unnatural world....having supervillains with various backgrounds and powers fits just fine.
That's mighty judgmental.
Says the guy who calls true fans of the comics superficial.
I'm simply more interested in the characterization and the story than visuals.
I'm interested in all of the above, not bits and pieces or only 2 of the 3 while having no interest in one aspect at all. It all connects and enhances the characters and experience.
So, while I may notice visuals, I don't go on for pages of forums about them and use them to conclude that they are not the "real" character, much less that anyone who disagrees doesn't care about the character.
Like it or not, in this umm..."visual" medium known as comic books (you know, those books that use PICTURES to tell stories?), the characters' appearances have a LOT to do with who they are. If you don't get that right you're missing half of what makes them great.
That's why I say you're superficial, because you only mention anything other than visuals when someone points out how only care about visuals. You imply that the entire character is inauthentic because the visuals aren't what you expect.
On the contrary, I've been pretty against EVERYTHING they're doing with Iris West right from the start, not just her PC race change. I've said quite a bit at separate and together times how much I vehemently detest the gag worthy childhood "in love with my best friend" dynamic they're forcing upon them (that's been crammed down our throats at least since
Friends - tv people want so badly to have their "Ross") along with the whole step sister bit and yes, psychologist bit.
Take for instance the job part. You see it is an unnecessary change. I live in a world where reporters do not show up for crimes in progress, or do anything at crime scenes other than stand far away and get rebuffed by beat cops. To me, if Iris is to be a part of the Flash's life, it is necessary for her to have a career change.
You're a novice who has never read a Flash comic then or willingly ignorant. Even her not showing up for a crime in progress, how would that prohibit her from interacting with Barry Allen or The Flash, exactly? She doesn't need to be right there in the action 24/7, and how, exactly, does making her a psychologist put her any further out in the battlefield, lol? Villains kidnap love interests all the time, reporter or not, who's to say Iris wouldn't be standing somewhere reporting on something peaceful and behind her a tragedy that requires The Flash's attention breaks out? For all your talk of "small mindedness", it seems like
you have a lot of room for growth.
Lol. It does perfectly and I have over 50 years proof of this.
For you, the reporter works, because you are much more concerned with the world the comics has built than trying to fit Barry's story into the real world, you consider any such fitting unnecessary, regardless of how appreciated it may be by non comics fans, or how much precedent Arrow set in doing so.
My philosophy is if it's not broke don't fix it. You want so badly to be defensive of any creative decision ever with little regard to the characters themselves you'll accept any change....the only thing you won't accept is good comics characters remaining as is for live action. The comics are no more or less "real" than your CW dramas, and making Iris West a black psychologist step sister love interest of Barry Allen doesn't add any more "believability" to anything, not to burst your bubble. You want so badly to see the characters change to accommodate tv and/or trends when tv and trends when the influence should be the other way around. Unlike you, I believe in this medium.
This is on top of the fact that just because something works doesn't mean it can't be improved.
If you really think you can "improve" something, go ahead, I'm all for getting the best of anything, but.....there have been no improvements.
"If it ain't broke don't fix it" is a great thing to say to get others to leave your stuff alone, but unless you know a lot about how something works, you really can't certify whether it's broken or not. If you do know a lot about how something works, missed opportunities for growth and deepening are your loss, even though they come with risks.
Well lucky for me I know a lot about The Flash and many other characters and how they work and I can tell you resoundingly that many of them DO work perfectly the way they are and don't need "improvement" in the areas you want to see it.
