I don't think Indiana Jones was as good as it should have been. It didn't feel like an Indiana Jones movie, and it wasn't nearly as good as Raiders. I liked it though, but it could have been much better.
Spoiler-
I thought that you could see the twist coming. Five minutes or so in, when the Soviets were asking about what Jones and some other people found and put in the box ten years ago, I figured that it was aliens because they were not only in New Mexico at the time, but the Roswell stuff happened in 1947. When they found the Crystal Skull, it was elongated. If anyone has read Domain(and spoilers for this too, but it was a great book. You should read it, but the sequel isn't as good) by Steve Alten, his theory on Kukulcan and the other people with elongated skulls were that they were aliens. It just reminded me of that, and it was further proof to me that somehow aliens are involved. At the end, I was disappointed, because I was right and saw it coming the whole time.
