Remakes have been part of Hollywood (and indeed the rest of the film industry around the world) from the very beginning. Some are done well, some ill. Certainly the ghastly parade of monstrous, because-we-can live action remakes of classic Disney animated features are a lamentable waste of celluloid. And those responsible for the crimes against cinema that are the remakes of Get Carter and The Wicker Man will one day have to answer to God.

However, there are a significant number of remakes that are as good as or even better than the original, and sometimes the definitive, classic version. These remakes include The Adventures of Robin Hood (1938), The Maltese Falcon (1941), His Girl Friday (1940), Ben Hur (1959), Invasion of the Body Snatchers (1978), The Thing (1982), The Bounty (1984), The Fly (1986), Cape Fear (1991), Twelve Monkeys (1995), Oceans Eleven (2001), True Grit (2010), and A Star is Born (2018).

Reboots or "legacy sequels" are another can of worms. Most of those are superfluous to requirements, with the odd exception (eg Mad Max Fury Road, which is almost as good as the first two). More on that subject here, again, if you're interested. :)
