I'm gonna come out and say that I don't think remakes are necessarily a bad thing. Three of my favorite films -- THE THING, THE FLY, and BODY SNATCHERS '79 -- are remakes, and improve upon the original in significant ways.
A lot of remakes are unnecessary, but what movie -- recent or not -- do you think could benefit from a remake, not just to make a quick buck but because there's unmined potential there of some kind? And, as a corollary (or maybe the whole reason to have it remade) -- who do you want to see do it?
Be prepared to make your case. If you say GHOSTBUSTERS you'd better have a damn fine argument and a hell of a director in mind.
Me, I'd like to see a new version of MORTAL KOMBAT, with either Prachya Pinkaew or Tony Jaa (the ONG BAK guys) at the helm. Give the flick some Eastern, contemplative flavor, while still getting a violence-riddled film befitting the original violent video game. Hook them up with an experienced VFX supervisor to help them get their bearings with the CG and I bet we'd see shit with Scorpion, Sub-Zero and Goro that'd blow our goddamn minds.
