my two cents..
Romancing The Stone (the visuals are still up to par no need for CGI and the interaction between characters still meets with todays ideals.. so why remake?)
Conan (come on.. seriously.. you can't do this without arnold.. he would not be conan otherwise.. I'm sure they are kicking in something from the books in order to make it new.. because that's the ONLY way to do anything with CONAN that can work
)
Akira (live action?? why??)
The Karate Kid (gotta be a black kid now because what.. no one will believe in a poor little itallian kid anymore.. WTF?)
Clash of the titans (ok, was great at the time, but I was a little kid, and seriously watching it now.. it falls flat despite the nice stopmotion. Action, direction, acting could all be improved and let's hope story get's a bit of a boost too.. it has not stood the test of time.)
footloose.. (ok.. forget it dudes.. it's not remake material.. it's do over material. That's not to say the first one was bad.. it wasn't. It's just that it was more about that actress and the plight of her character.. if you try to follow the first one it's a fail, and if you do it new, it's not footloose.. )
Red Dawn (again, can't improve upon it. The movie still chills you and aside from date references there is no need for update)
short circuit. (top notch robotics to be what.. replaced with CGI? please excuse me while I go vomit. )
The thing (again.. top notch VFX and still super scary.. they're going to throw in some CGI.. why not just do a starwars retouch thing to them.. that might work if they spent enough time with it)
The birds (still freaky, and it was great because of how it was done, hitchcock intentionally refused to show things to make it more scary.. now they are going to throw in CGI and make it into a hunk of obtuse crap..)
Poltergeist (still works.. again, CGI won't make this better.. and adding in crappy actors will only make it worse, and good actors will make it the same as it was so why bother)
childs play.. (couldn't be any better or worse.. stupid idea to begin with.. )
Rocky horror picture show (this is a cult film.. you can't redo these and succeed.. I don't know why they are trying.. they obviously missed why it's still loved and watched EVERY halloween... they are doomed to fail)
Flash Gordon (ok, doing scifi with cardboard and wooden sets and such just doesn't hold up to todays standard so I can understand this one.. it's old enough to remake and it's VFX were bad enough to be worth a redo.. )
jetsons (live action.. hello.. flintstones.. it sucked and it had star power.. why the f..ereknd;lfkadhpihefaeg GAHHHHHHHHH!!! let's destroy a classic with stupidity)
last starfighter (even with it's dated CGI it works.. it all worked and all the new CGI is going to do it make it slightly different.. not worth touching)
Red Sonja.. (again Arnold.. sorry.. won't work
)
Highlander.. (let it rest dudes.. let it rest.. )
