Only movie remake that springs to mind that I actually enjoyed right now is The Day The Earth Stood Still with Keanu Reeves, loved it! There are probably a few if I thought about it though.
Disney movie remakes on the other hand, I used to think it's a business decision to make money, of course they probably love milking it and making as much money as possible but it's really just a way to inspire new appreciation for old classics.
I guess Disney films are considered classic stories, Shakespeare plays are always relived and reenacted, just like old songs by Elvis, The Beatles, James Brown, Michael Jackson etc are all classics and constantly covered & remixed, told in a new, fresh way, same story but apply modern creative and artistic methods. And it's a way for new upcoming actors and actresses to showcase their talent and be part of stories they loved in their childhood.
Personally speaking, I don't like any Disney remake, but I was a huge fan of Disney growing up, I loved me some Disney as a kid.
