Superheroes - light or dark?

[CaptainCrazy]

So how do you like your superhero films – light or dark in tone? It doesn’t matter to me as long as it has a good story, strong direction and not Batman and Robin.

However, on every message board I always see arguments about tone, for example, why is FF so light (read the comic book, you nerd), or why is Superman (or Iron Man 3) so heavy like The Dark Knight or “…insert generic internet nerd rage comment here…”?

What are your thoughts?
