This movie is based on the dumbest concept I have ever come across in Hollywood. But it still manages to entertain and it does so beautifully. It was one of the funniest movies I say in the last 12 months. And some of the humour was actually very good - not just slap stick as one would expect in a movie like this. I liked it best because of its offbeat and daring concept and good humour. Some of the twists in the plot were so wacky that they came across as actually very smart. The acting and production values were very good as well. Id include it in the list of the Top 10 comedies of the year.
