Besides the fact that Benigni truly underestimates how horrible life was in concentration camps (a kid can't just stay hidden without food for a couple of days in a dormitory), I don't really get anything out of this movie. Using your imagination will get you out of a Nazi death camp??
Roberto Benigni carries the show by interpreting this very likeable character.
I think it's a bit questionable that the director molds history so he can tell his own story, especially when it's about the Holocaust.
