Danny Boon and Diane Kruger are good actors caught in a bad situation: Un plan parfait lacks the most important things in a comedy: a good script, good dialogues and a good director. What is left is a mess, there is often no logic in how the characters behave, there are plenty of plot holes and the whole story doesn't make much sense.
I think it's good to remember that French production companies are heavily subsidized (directly and indirectly)by the French government, because of that delivering quality Cinema is not their main purpose, instead they try to maintain a yearly output that will allow them to claim these subsidies.
The end result is that over the last decade there was only a couple of good French films released each year, and all the rest is, if not shockingly bad, mediocre at best.
Un plan parfait is in this category, a movie made for money, not for viewers' pleasure.
