1) Last Crusade - Ford and Connery played off of each other very well
2) Temple of Doom - this should be third but nostalgia drives the ranking. I was young and shortround really allowed me to connect with the movie.
3) Raiders of the Lost Ark - just a good movie
4) Kingdom of the Crystal Skull - "Look what they've done to my poor boy"
Unranked) Dial of Destiny - Yeah after Kingdom, I'm not in a hurry to watch a really old Harrison do stunts while likely having the writing drag down a series I was always fond of but have now lost faith in.
