I think that when it comes to superheros people want to see them in a lighter sense. With the exception of Batman and Wolverine. Superheroes are meant to stand out and shine, but even then some comics had their dark moments. Like when Spider-man accidentally kills his girlfriend in one issue. I think some people want darkness just not all the time.
The Amazing Spider-man was great. I felt it kept to the original comics a lot better than Sam Raimi's Spider-man. I thought the actor was great at being a sarcastic teen, Gwen Stacy was his girlfriend and not Mary Jane, and he had to create his webshooter.
Also Superman sucks either way. He's OP.
Though I tend to like the darker stuff.
Also Captain America was great, and so was Thor.
