I can’t think of a single bad movie that could have been measurably improved by throwing more money, time, or talent at the crew. I can forgive a whole lot of shoestring-budget production-value-poverty. To my eye, bad movies are bad because of some combination of bad direction, bad acting, bad editing, or especially and most commonly, bad writing.
The Phantom Menace is a perfectly cromulent movie with the dialogue track muted. It only really falls apart when you hear what the characters are saying.
