That's your personal opinion. I personally wouldn't put something completely forgettable on a list. And like I said, some of the this decade's more well-known comic book adaptations have been critical and commercial successes (see: Batman Begins, The Dark Knight, Spider-Man, Spider-Man 2, Sin City, etc.).
That's not including quieter genre films that are also comic book adaptations of the spandex-free variety, such as A History of Violence, American Splendor, Ghost World, Road to Perdition, etc. Scott Pilgrim also looks ace.
If you're going to narrow it down to a sub-genre of a sub-genre (namely the superhero), guess what, the pickings are going to be slimmer. And even then, Iron Man doesn't fall into the vicinity of the top ten release within the past ten years.
And if a sub-genre of a sub-genre can put out ten entertaining to legitimately good films within a decade, that's pretty fucking good. That's like saying, "Man, there aren't a ton of good ghost movies that involve haunted houses!"
