Maybe Temple of Doom's problems (racism, Kate Capshaw) outweigh its positives, but I feel like what's good about the movie is often lost in the discussion of it. It moves at a crazy pace and the action is top-notch, especially from the mine car through the bridge. Effects may not hold up on the former, but it never really bothers me. I know the grossness and violence and darkness is a sticking point for some (a child is literally like "I wish I would die"), but the more I've seen it the more I appreciate how wild a decision that was.
And the "Nice try Lao Che!" moment in the opening is maybe the second funniest moment in the entire series, following Raiders' swordsman scene.
