I really think they went all out on this one. It had a different yet similar feeling to the previous movies. They definately didn't set out to "remake" any of the previous movies. The adventure is very different and quite rich in story. I liked how they incorporated the big events of the time (the Reds, the atomic age, and Roswell/A51) in the film. Harrison was top notch as always and will always be Indy. Shia was an awesome sidekick and very likable. The humor and action were all there. My only complaint was the ending was a bit confusing, but maybe if I see it again (which I will), it'll be more clear. I'd love to see a 5th film but who knows.
