To appreciate the full nuances of this movie a very good grasp of German and particularly Bavarian slang is a must. Without it it's simply an average slapstick comedy and any review of it is destined to miss the mark. The movie simply lives from the German dialogue, especially the slang. I'd say watch it in English or subtitles, by all means, but don't write a review since you probably missed 50% of the real funny stuff. It'd be the same as writing a review about the German dubbed version of Romeo and Juliet. Why bother?
