He played such a different character in each one, though. The basic theme was there, but each movie he acted a little differently. You can't really say, "Well, in temple he acted most like Indy" esp. since he acts different from one that came out first. But you can't really say "He acted best in Raiders because it was his first and set the precedent" either I don't think.
So I'm just going to answer the question, "Which Indy character did I like the best" because I can't really compare the exact characters of the three to each other. Am I thinking too deeply into this? Anywho, my vote goes for raiders. LC is my favorite movie, but I like the raiders "Indy character" the best.
