*ICK*, I thought the bastardized movie version of
The Punisher was a horrible adaptation of the comic book. Wasn't as Godawful as
Judge Dredd or
Howard the Duck (nothin' is), but horrible just the same.
Best superhero movie for me is still 1978's
Superman: The Movie. Captured all of the requisite basics of the well-known story, slightly updated with winks and laughs, brought to life very well by Richard Donner and company with top-of-the-line effects for their day. Fun, star-filled excellent casting - Hackman as Luthor alone was a stroke of genius. Still holds up well today.
Warren Beatty's
Dick Tracy (1990) is lots of fun too, and the graphic style of duplicating the comic strip color schemes and perspectives is endlessly fascinating. It's more flawed than
Superman: The Movie, but damn good anyway. Don't know if you consider Dick Tracy a "superhero" or not, but it's a great comic brought to life.
Men In Black has all of the fun of the comic book, capturing that deadpan humor & clever tone spot-on, plus the big movie-star casting of Will Smith and Tommy Lee Jones that works absolutely perfectly and adds another layer of charm. Here's hoping the second installment continues the fun. If agents K & J aren't superheroes, who is?
I think the best comic book adaptation yet is
Conan the Barbarian (1982)...yes, even better than
Superman: The Movie. But again, I don't know if you'd consider a bloodthirsty, sword-wielding thief and bezerker a "superhero" per se. He doesn't wear tights or stop super geniuses from taking over the world, but I love him all the same and gush about John Milius' classic regularly.
Two that are fantastic in their own way if you just let yourself go with the all-out campiness and diliberate cheese, are
Batman (1966) and
Flash Gordon (1980). Both are hopelessly dated in the eras which they were made, but that's also part of their charm (for me, anyway). Can't be viewed critically at all, only as pure fun - which they surely are.
And there is an existing thread where some of us discussed this a bit,
HERE. That one asked for favorites/least favorites of comic book and video game movie adaptions.
