Its not like the remake makes the old movie go away.
Remakes can be better. Especially things that deal with alot of cgi. Or has the potential to.
The only exception (and its kind of different anyway) is Hollywood trying to make live action anime films. Just don't.
I agree with this. I usually don't like it when they make live action versions of cartoons because sometimes the exaggerated formats with cartoons sometimes doesn't work with live action movies. However, there were some live action movies that did do a good job with adapting cartoons.
I don't think Marvel could do X-Men or Spider Man at the moment since they are owned by different studios at the moment. However, I would like to see either Spider Man or Fantastic Four cross over since they seem to fit more in the Marvel Cinematic Universe, that's if Marvel gets the rights back. I think for now X-Men should stay in their own universe since they have too many characters as it is, although I would love to see how Marvel portrays the X-Men.
