To be fair, that's mostly because there have been so many in just the last eight years. Off the top of my head there's been 3 each from Blade, Spider-Man & X-Men, 2 (not very)Fantastic Four movies, 2 Hulks, Daredevil, Elektra, Ghost Rider, one Punisher film (with another on it's way) so that's what? 17? With another half dozen or so due in the next 2-3 years. Now DC on the other hand has had *counts on fingers* three movies in that same amount of time so it's no wonder the batting average is a little skewed in DC's favour. Still, you could argue that DC have just been more careful with who they allow to develop their properties, possibly due to what Joel and his neon electric rubber nipples did back in the 90's. I can certainly see why Marvel seam to want to take more direct control over what gets made from here on out but I think it'd be naive to expect everything to be of the same standard of 'Iron Man', but at least I think we won't get another 'Fantastic Four' style dud.
