^ Maybe if Lucas didnt fire Darabont you would've gotten a better movie.
Wrong. The Darabont INDY IV script is probably the worst work of his career. It really reads like hackneyed fan-fiction, and also has some of the worst one-liners ever. I didn't want to believe it was legit. I still don't. It's shockingly bad. So much so that I'd dare say that KOTCS (with all its own faults) turned out better than it would have had they used that one.
The only thing Darabont got right that the movie screwed up was the Marion character, who's just a complete fool in KOTCS. But that's not nearly enough to save his sophomoric effort.
