First, I enjoyed this move. It's another in a long line of additional films in successful franchises, and as "just another episode in an olde time serial," it was fine. However, taking it out of the era in which we came to know him so well and dropping Indy into the '50's is pretty jarring. This means the movie had to use a lot of throwaway lines to explain how things came to be, and that just didn't work that well. My biggest complaint is that a great deal of the plot was lifted from the Brendan Fraser "Mummy" franchise. There's nothing new, and too much unexplained here. But in the end, I came out of the theater whistling the theme and hope there might be another Indiana Jones movie. Maybe with mummies.
