I don't remember if I saw this movie on the big screen when it came out, but I have watched the full series many times on TV. The movie was a joy to see on the big screen with an audience. Many details jumped out at me that I hadn't paid attention to on the little screen. My son and I had a totally enjoyable evening at the AMC in Yorktown.
I haven't read the book so I can't comment on any deviation from the original story. However, the sentiments and points of view in the movie correspond with my experiences visiting former camps in both Germany and Austria and discussions with Austrian nationals. It is too serious a topic to say that I "enjoyed" the movie. It is thought provoking and does an exceptional job of portraying a young child's attempt to harmonize his beliefs about what is good and right and honorable in the face of his growing awareness of the horrors on his doorstep. I did think the ending was over the top.
This isn't the best Indy movie but it is a fun ride. It was outrageous and funny and full of great action sequences. There is good and evil, stupid government officials, and old friends. What could be better? Definitely should be seen on the big screen.
