This was a very well done movie and the goal was clearly to make you feel like you are there in the middle of the war and more specifically - in the tank. That mission was definitely accomplished. The intensity was great. The characters and their different levels of acceptance of where they were was great. The only major knock I can make against this movie is that it was simply too long. This could have easily been 30 minutes shorter and there were various scenes that looking back were not necessary whatsoever.
I would still recommend people checking this out. It is a very good movie and could have been awesome if there wasn't such an overly long running time.
