I repeat, would you like to put a friendly wager on it? Bragging rights, since that's the easiest thing to do over the 'net.
Guys, name me a film where they drastically changed the source material and it turned out good. I can think of one, Forrest Gump (dear Lord, that book was awful). Now, take a look at how many of those were based off of old TV shows (say, from the 80s and 90s) or even most older films and see how many of those were good (since they're trying to appeal to both the 18-29 and teen age group).
Take Alien vs Predator for an example. Why the fuck do you make a PG film that's based off two R films? Easy, you try to increase the appeal. Or Dukes of Hazard. So, you don't think they're going to fuck with this to try and make it appeal to more than just the original fans? That's a certainty, it's how much they fuck with it that's the question, not if.
There is at least a 95% chance this film will blow chunks, 4% chance it'll be tolerable, and 1% chance of being good. I'm basing this on my experience with movies of this type. I will admit that because I loved the original material so that those figures are skewed, but only slightly (5% or so).
Also, since you guys all like to say "you're just ranting, shut up", maybe it'll be your turn to shut up, which is why I'm proposing the wager to begin with. Particularly since any time I dare to express my displeasure with anything on any level, no one ever says "well, let's see and then we'll prove you wrong" it's always "you're always ranting about everything, shut up". Which, of course, isn't true, considering how many movies I praise. Of course, that goes completely unnoticed......
