All right, I can agree with you that there was a different feel between Avengers and Man of Steel in terms of the destruction (more humor in Avengers), but I still submit that most of your complaint is just your perception of it. Because I didn't realize that it is specifically buildings collapsing which stresses you out, not just the inevitable collapse later from all the structural damage, or the chunks raining down on innocent people, or explosions, or whatever. If it is strictly them falling down, then ok, there is nothing I can offer you because Man of Steel definitely has more of that.
But to be fair, you should go watch Man of Steel again (you can skip the first 20 minutes, I'm not an asshole) and report back all of the "realistic imagery of humans dying" so we have both sides of your complaint to compare. Or just say that it is specifically buildings falling down that bothers you. I can't argue with that one.
And so we're clear, I've said many times before that if they had just spent 15 seconds showing Superman attempting to flee Metropolis, only to have Zod say nope and smash some buildings until he came back, it would have been a thousand times better in that regard. They didn't have him do it though, and that is pretty much the thing that everyone hinges their complaints on, so I'll admit they fucked up. And Avengers was a vastly better movie in almost all regards. I just think you're choosing to view the two movies through different prisms, or one particular phobia. Which I've already said is your right, I just have the right to disagree as well. Which we do all the time, so no big deal, just something to argue about while TV is slow. I still love you man.
