I liked that movie. Yeah, it was probably brutally unrealistic, but it was still entertaining. The American mission depicted in the movie didn't happen and I guess that's something people don't understand. It even lists the actual Enigma captures at the end. And the depth charge scene is amazing- if your sound system can handle it.
But maybe I just have horrible taste, because I found Das Boot unbelievably boring. It may be more authentic, but it was boring. I would- and I am quite serious here- take U-571 over Das Boot any day.
Then again, I am the same guy who created SH3 Retarded: Nazi Cocaine and I don't like GWX either. So maybe I'm just the devil's advocate of the forum.
