I may be in the minority with this, but I honestly think Man of Steel was the worst superhero movie I've seen.
I could go on and on about how ridiculous it was to make Superman dark and edgy (traits that are the total opposite of the character), but there was just so much more wrong with it in my eyes.
First of all, literally half the movie had no plot. Like, it was just explosions and destruction. No story going on.
Then there's the fact that Superman just didn't even impress as a character. When I think of Superman, I think of these crazy and imaginative feats of strength that he performs. That's what makes Superman fun to watch, and it's been pretty much like this in every other version of him.
But in Man of Steel, there wasn't really any of this. Sure, they showed him fly around really fast and fly through stuff, but seeing him fly really fast through stuff got boring after the 147th time.
Forced romance with Lois Lane felt awkward. Enough said.
Stupid plot points that didn't even make any sense which I won't mention here due to spoilers.
No personality in the film whatsoever. Horrible ending. Completely ignored the traits of the character and almost seemed like an insult to the series.
I'm a big fan of superhero movies. Even the ones I didn't really like (like the recent Spider-Man movie), I find some aspects that I think are cool. But Man of Steel may be the only one I've seen where I honestly hate every aspect of it.
