I don't get all the remakes either. Some turn out ok to good, but the most are awful it seems (particularly the big "60/70s TV Show Made into Movie" kick over the past couple years. I personally hate to see some of them get remade again, Karate Kid being a good example. It may be cheezy, but I enjoyed the heck out of the first one as a kid (and liked the 2nd one well enough at the time too). To make it worse, I've read rumors (or maybe it is confirmation) that the new Karate Kid is being done by Will Smith - starring his son in the lead role and I believe Jackie Chan in the Miyagi-ish role (I don't know if he is supposed to be the same character or not, I'm guessing not). Yikes.
I have often wondered if the Original Trilogy would be remade some day or not. I'm guessing the majority of the fanbase would rather not (probably all of the fanbase), but for some reason I could still see it happening. Hopefully not. I wouldn't mind seeing the originals released in theaters again though, but we'll probably have to wait for the 3D versions we've been hearing about for years now.
