At What Age Do Superhero Movies Stop Being Cool?

Okay, we've got Spiderman, Batman with Superman, The Hulk, Captain America and The Avengers coming out next year.  The question is; are there too many comic book movies coming out at one time?  And the bigger question, at what age do you stop going to see a comic book movie?  I grew up with comic books so for me its unbelievable that they can make a a live action movie look just like it did in the comics, but more important than that today they can make a movie that looks better than the comics.  I am in awe every time I see one on screen, but every date I take with me, can't really get into it.  The phrase they always leave me with is......grow up.
