Am I going to see the Karate Kid? No, but I bet a lot of people are.
I bet a lot of people will see the new Spider Man reboot, too. Why? Because people like Spider Man. They'll see the Spider Man reboot the same way people saw The Hulk reboot. Yeah, remember The Hulk? The movie that was rebooted a mere FIVE YEARS later? If I'm not mistaken, some people actually like the reboot (The Incredible Hulk) better than the original Ang Lee version, which proves that maybe reboots aren't always a bad thing.
For that matter, how many reboots do we actually get each year? Of those reboots, how many were based off a movie released in the last ten to fifteen years? How many were considered good enough NOT to need a reboot? I know people on this site like to go on and on about how many reboots Hollywood has been cranking out, but if you stop to think about it, there actually hasn't been a ton of reboots. Sequels? Yes. Prequels? Yes. Book adaptations? Yes. But reboots? Not so much. Most of the reboot talk actually comes from unhappy fans, and Hollywood picks up on that, so we're the ones who are partially to blame for "reboot mania" in Hollywood. Really, if you were given the chance to reboot Fantastic Four (1 or 2), Daredevil, X-Men (1, 2, or 3), Wolverine, or Super Man Returns, would you tell the studios NOT to do it just because it's too soon after the original came out?
I don't think reboots are the horrible things people are making them out to be, because reboots, though they have the same characters and the same basic story lines, are always different from the version that came before them. When are the reboots the exact same thing as the original? Do you think the rebooted Spider Man is going to have the exact same story as Sam Raimi's Spider Man movies?
Do reboots get boring after a while? Depends on how they're done. A good reboot can be better than the original (Batman Begins and The Dark Knight, anyone?). Are original stories better? That depends on how they're done, too. Original stories can suck just as bad as any reboot, if not more.
