Good movie. Just a few unbelievable parts. *SPOILERS* Ok. How could that dingy car, and more surprisingly, all those people, survive that humungo waterfall? Too unbelievable. Also, when she drove the car onto the tree and it brought them down slowly...too lucky. Also, the ending I didn't like that much. Aliens in an Indy movie?!? I think it would've been better since that lady wanted to know 'everything' if her skull started to grow, then she disintegrated into another crystal skeleton with a crystal skull. That could explain the crystal skulls and be a supernatural ending without turning Indy into a scifi. Other than that, great action sequences, great job on using Indy's age in the movie, and good connections to the other movies. Definetly worth the ticket, but again, the ending should've been different.
