Snyder is a bad source for discussion about "darkness". He tries to be edgy to be "edgy".
Winter Soldier, as good as it is, still loses a lot of "darkness" points for chickening out on the central conceit. Frankly, Iron Man is the most dark movie, because it deals with real world violence and war.
Yeah for sure Iron Man is the darkest. And it shows you can make a serious movie and still have it be fun and exciting.
Those cave scenes were not played for levity or laughs at all. It felt realistic or at least as realistic as a concept of Iron Man can beThe whole scene of Tony flying over and killing the terrorists, there was weight to the action scenes, etc. It's funny though because it's no darker than the standard blockbuster up until about 2012-2014 when most blockbusters, not just the MCU, got really sloppy with their tones.
----------------------------
I think CW for sure is not really dark or "serious." I never got this take. It tries to but falls flat. Like it's a bunch of half measures similar to what Sithborg says about TWS.
-There are moral dilemma questions that comes up heavy in Act 1, but by the end of the movie (and for sure in the MCU future) the moral dilemma isn't even the crux or emotional core. Bucky is. So the moral stuff seems to only serve to have the Avengers arrested, which they could've done by just having them all side with Bucky.
-The heroes splinter, but it's kinda hollow because Cap sends Tony that message that basically was "Well that escalated quickly. I mean that really got outta hand! But we cool right? Well if you need me, I'm around"
-The heroes all fight, but you have silly stuff like "You're pulling your punches" and "We're still friends right?" and so many of them are firing off jokes or have comedic bits during it that all the weight or "darkness" of it is gone. It's just the cinematic equivalent of a kid taking his action figures and smashing them together.
-Rhodey gets crippled but he doesn't blame any of the them and he gets his robotic walking helpers, so it's kinda like what's the point of that?
-Team Cap is arrested, but they're broken out by the end of the movie.
-Team Cap has to go on the run but they seem relatively fine when we next see them in IW. Cap is really they only scruffy one. Falcon still has a fresh cut, Widow still looks good, and even Wanda finds a way to meet up with her love interest. You don't get the feeling that being on the run really affected them much. Hell even Tony doesn't seem that that affected the next times we see him in Homecoming or IW
-Bucky killed Steve's parents but that never really comes back up in later film so again it's kinda like what was the point?
-Them lowballing the number of deaths in all those major MCU events
-The ending isn't happy, but someone said the realest thing about CW. I forget who the member was but they said "I don't expect anything that happened in Civil War to really matter after the first act of IW" and I think I kinda feel that. Of course the Avengers are split up and that's the big thing, but the reason Tony doesn't call Cap isn't because he's mad at him. It wasn't like he threw away the phone and said "Forget Cap, we can stop Thanos ourselves." (which I think would've made it better and way more heartbreaking if that's why they lost).
-I for sure don't think the ending is pessimistic as all. As I stated before in the other points most of the stuff like: Tony and Steve fighting, Wanda and Vision going their separate ways, Team Cap being in prison, Rhodey being seriously injured are kinda handled with kid gloves by the end or are resolved by Act I of IW.
All of that doesn't seem that dark or serious to me at all. It's serious the same way a butter knife is sharp. And no I'm not saying "it's not serious because it's not TDK, Logan level of serious and dark." But I still don't think taking a bunch of half measures makes for a serious or dark piece of work.
If anything I say IW is way more serious feeling due to feeling of desperation and pain the heroes have throughout. Sure everyone who is dusted at the end is undone in EG, but yeah that feeling of desperation, all of those scenes with Thanos is on screen, the death of Gamora which wasn't some cool sacrifice myself to save everyone thing, Peter "I told you to go left" scene on Knowhere are really more mature and serious than anything done in CW. I mean I guess grading on a curve, it's more serious than most of the other MCU. But that doesn't say much. Especially compared to the first Iron Man or IW.
