I think Iron Man doesn't get credit for everything it has going on. Without deconstructing it scene by scene and/or repeating my posted review, I'll just say that the gap between The Dark Knight and Iron Man is not that wide for me. On the other hand, while Hellboy has been a decently made adaptation of much less accessable and obscure source material, it lags behind these other two (three, if you include Batman Begins) films.
Iron Man 2, on the other hand, was a disappointment bathed in mediocrity worse than Carrie got doused with pig's blood; I have not yet seen Hellboy 2 start to finish, but I will say that Guillermo Del Toro style is so pervasive that it's beginning to become redundant. Placing eyes in strange places can't be groundbreaking forever.
