Why not a comedy?

This film is rather bad. It has some few laughs, but I don´t understand why they didn´t decided to make a full comedy instead of adding all the tragic and political sides. People hiding in closets, actors swearing, misunderstandings and ironies, all that fit; what doesn´t fit is having a "happy ending" in which we see one jew (out of dozens shown) saved, or the fascist member of the crew going through the admission process to a concentration camp. You cannot laugh at that, and you feel like an idiot for laughing at everything else.
