In my mind, the only West Side Story film that matters
is the one done with Natalie Wood, her costars and that spectacular music score. Some things do not need to be redone.
Beauty & The Beast often works as a redo, because certain changes to the cast or the music don’t seem to distort the core story. Sometimes, as with actress Emma Watson, the “Beauty” doesn’t even need to be all that beautiful.
I'm a fan of both Marni Nixon and Jimmy Bryant, so tough act to follow imo.
