Has anyone seen this?

"In the last moments of World War II, a young German soldier fighting for survival finds a Nazi captain's uniform. Impersonating an officer, the man quickly takes on the monstrous identity of the perpetrators he is trying to escape from."
I absolutely loved the first 45 minutes or so but after that it got silly and boring but still worth viewing nonetheless. Just was wondering if anyone else has seen it and if I was the only one kind of disappointing with it?
One great thing is that it is a full German war film instead of seeing it told via the Allies side.
