I saw Man of Steel with my dad for Father's Day, and I have to say that, as far as superhero films go, it was nothing outstanding. It wasn't outright terrible either, and it did have some spectacular CGI moments, but then all the recent superhero movies have those. If I could describe Man of Steel with one word, it would be "generic" or "mediocre". In fact I would use those some descriptors for the majority of superhero movies I've seen in the past few years, because they're all starting to look alike. I say Hollywood needs to give the superhero genre a rest for now.
Come to think of it, I always found Superman himself as a rather bland character. Most other superheroes have unique personality characteristics and design motifs (e.g. bats, spiders, Norse mythology, or American patriotism) that set each of them apart, but Superman doesn't really have anything defining him other than a general "super" quality. While that can probably be attributed to his being one of the earliest superheroes ever conceived, now that DC and Marvel have invented all these other colorful characters, Superman seems today nothing more than the most basic archetype of a superhero. For that reason I find him remarkable only because he's so unremarkable.
