I'll have to read those reviews to see where the critics felt it went wrong. Maybe too many expectations got in the way. Maybe they expected a fun summer superhero movie and didn't get it. Maybe they even expected a Superman movie. Well, I'll tell you right now, it's not your typical summer blockbuster and it's not a Superman movie. It's an alien invasion drama/horror/action piece that just happens to use elements of Superman as dressing.
I loved it.
It wasn't a perfect movie, but I'm giving it a perfect score anyway because it radicalized Superman and succeeded. I watched and left the theatre feeling like I had seen something new. A rehash, this wasn't. Though it did have a few homages here and there.
Oh, and the suit totally works in the context of this movie. You'll see.
