6. 'The Hangover Part II'
The odds of a single group of friends waking up in a hotel room with a missing friend and no memory of the previous night is pretty remote, but audiences are happy to accept it for the sake of the movie. The odds of it happening twice, however, are ludicrously remote. Worse than that, even with the action taking place in Bangkok as opposed to Las Vegas, it results in a movie that hits all the same notes of the original. People flocked to the movie based on fond memories of the original, but most walked out quite underwhelmed.
