It recently dawned on me that, despite over a dozen viewings over the course of my life and all my attempts to like it, I simply do not enjoy watching Temple of Doom. With that perspective, I need to watch Crystal Skull again sometime; the 2nd half of the movie is trash, but I remember having a pretty positive opinion of the movie overall in the first half.
Couldn't pick a favorite between Raiders and Last Crusade. Raiders had Marian, bringing a gun to a swordfight, and one of my favorite endings in movie history (also, Indy getting dragged by a truck is the first stunt I ever saw as a kid that made me sit up and go 'wow, that's so cool.'); Last Crusade had Sean Connery, Brody and Sallah in more active roles, and was overall more fun, varied, and adventurous.
Simple questions deserve long-winded answers that no one will bother to read.
