It's a ride that needs updating but not removing completely.
All they need to do is change some of the movies for more modern hits, maybe redo the themed sections (westerns and gangster films aren't hugely popular these days) and write a new script (at this point I can recite it pretty much word for word), but other than that the mechanics are fine and the theme matches the overall "movie studio" idea behind the park.
It would be a shame to remove every last vestige of what the park once was, especially as there are already so many changes currently being made.
