I was recently watching Nakache's "Intouchables" and that reminded me of this one, a story of how one man's appearance changes the dysfunctional dynamics of a large family. I was staggered that this movie has an IMDb weighted average of 4.4 (I see it's actually 8.4; must have made a mistake the day I wrote this review. Apologies). I regard it as one of the best comedy movies I have watched. The film is so successful in what it set out to achieve it appears effortless. Presenting a complex idea in a simple story that provides clean fun at no one's expense, it is an uplifting fantasy that should appeal to a wide range of audience. The actors are almost natural in their roles and do not have to resort to desperate frivolities to elicit a laugh. Similarly, there are no noticeably stylised camera shots that distract from the narrative.
It is not a crude comedy and no one should expect a Johnny Leveresque crassness and that is the strength of this film. This film is fun but it hurts no one in the process and that is a hard act to pull off indeed.
