I challenge anyone here to name a remake that was better than the original.
Ben Hur (1959) springs immediately to mind. A number of movies in various comic book franchises would probably also qualify. Does anyone really think the Adam West Batman movie was better than the Tim Burton version? (I can get that some people might prefer the Tim Burton version to the Christopher Nolan version, though that would be more of a judgment call.)
It's also good to remember that the whole reason people tend to do remakes is because the original was good enough to be worth copying. With the possible exception of movies based on an original work in another medium (book, play, graphic novel, etc.), nobody is going to bother making a remake of a stinker. They're going to pick the stuff that was great and successful to copy, which inherently disadvantages the remake because it's being compared to something good.
