While I've never thought this movie was perfect, I've always considered it a classic. If nothing else, it deserves serious props for being an original idea. In an age when all we seem to get a remakes and sequels, that should mean something.
Of course, there's been off-and-on talk about a reboot for this franchise too. But it is one case in which I think a solid trilogy planned from the start and shot back-to-back would do more justice to the concept than the original. Especially if they kept the awesome soundtrack.
But I don't have enough faith in Hollywood to do it right.
