This is Marvel though. The company itself has only made Incredible Hulk, Iron Man and Iron Man 2. They have a pretty good track record right now for live action... although their cartoons tend to be awful more often than good.
This is truth. Marvel films have a much better track record then DC films
Personally, I think they hit a dude when they try to do fanservice or a character thats blah to begin with. I will start with 1986...
Great: Iron Man, Iron Man 2, The Incredible Hulk, X2 X-Men United, Spider-Man, Spider-Man 2, Blade, Blade II, Planet Hulk, The Incredible Hulk Returns,
Good: X-Men, Fantastic Four, Spider-Man 3, X-Men Origins: Wolverine, Ultimate Anvengers, Ultimate Avengers II, Hulk Vs, Next Avengers
Mediocre: Howard the Duck, The Punisher (1890), Captain America (1990), Daredevil, Ang Lee's Hulk, The Punisher (2005), Ghost Rider, Fantastic Four Rise of the Silver Surfer, Punisher War Zone, Doctor Strange, Trial of the Incredible Hulk, The Death fo the Incredible Hulk, Capgtain America (1978)
Total. Crap: The Fantastic Four (1994), Blade Trinity, Elektra, Man-Thing, Generation X, Captain America II: Death Too Soon
There's ALOT of below the belt stuff there - movies that didnt need to be made, or mad badly because the flag ship titles are bringing in the dough..
Now DC, I'll start with 1978:
Great: Superman, Superman II, Batman (1989), Batman Returns (1992), Batman Begins, Batman The Dark Knight, Watchmen, Batman: Mask of the Phantasm, Superman Doomsday, JL: New Frontier, Green Lantern First Flight
Good: Superman Returns, Swamp Thing, Supergirl, Batman & Mr. Freeze Subzero, Wonder Woman (animated), Batman: Gotham Knight, Superman/Batman: Public Enemies, Batman: Under the Red Hood
Mediocre: Superman III, Batman Forver, Jonah Hex, Batman: Mystery of the Batwoman, The Batman vs Dracula, Superman Braniac Attacks, Teen Titans Trouble in Tokyo, Tales of the Black Freighter, JL crisis on Two Earths
Total. Crap: Superman IV The Quest for Peace, Batman and Robin, Catwoman, Steel, The Return of the Swamp Thing (but I LOVE this film), Superman II the Richard Donner Cut
Personally, I can see the line here. DC knows what can make a good movie and backs it, Marvel tries to experiement but then half-asses it. IMHO.
