I was prepared for this film to be as bad as other over-hyped french comedies. I expected to commit suicide after 20 minutes but, surprisingly, the movie was much better than I expected.
The scenario shows some good ideas, even if they are far from being fully exploited. But the real surprise is that the Tuche family is actually so nice that it becomes impossible to hate them. And that is the only reason why this movie is pleasant. Yes I admit that many parts of the script are really unbelievable (no real spoiler here: their posh neighbors liking the Tuche family far too easily and many other situations) but the scene with the bank director is the central piece.
Overall, it should have been a very annoying movie, but the kindness of all the characters makes it not that bad.
