I think the biggest part in this really is that these figures mean nothing to me as opposed to you guys who grew up with em. Sure, they made origin stories, but its not the same as a literal childhood hero or at least an established universe to connect it to. So I think its very normal I have a very different point of approach.
Also I did say they make good quality movies, I'm not saying everything sucks at all. But lets be honest here, the title, Civil War, is a bad fit for the movie. I came into the movie expecting shit to go down, but it did not. Dark(er) tone and grim faces do not make a war. Well, a cold war perhaps.
So yeah, that was disappointing.
If people shit on BvS (deservedly so), for the actual fight being unimportant, build up strangely, and really weirdly concluded, and the main point of it being that its dark and gritty, then this Civil War should get a similar treatment. Of course that movie had a whole bunch of other problems that made it inferior to CW.
