As others have probably suggested in the thread, remakes no one wanted but turned out to be as good or better than the original would be an interesting offshoot discussion.
The one film that I find a genuine one-off is The Fly. It has had not one but two remakes, and imo they’re all as great as each other. Wouldn’t want to pick a best one because they’re all different beasts, and classics in their own right.
At the other end of the spectrum, how many fucking versions and remakes of A Christmas Carol has humanity been subjected to over the decades? The Muppets one is okay though.
