Although I enjoyed the movie, it was too long and sagged in the middle a bit. The de-aged Indy looked brilliant at the start and they just about pulled off the outrageous climax. But I don't understand the significance and importance of the moon landing to the narrative - it had nothing to do with the main story at all really. It would have worked if Indy somehow blasted off to the moon himself at the end. Instead, we got an even more implausible ending to this famous film franchise.
