20. 'Pain and Gain'
Somehow or another, the combination of Michael Bay, the Rock and a ripped Mark Wahlberg didn't make for a classic motion picture. It aimed for comedy and action, but managed to fail on both ends. Our hopes are very low for the upcoming Transformers 4 that re-teams Bay and Wahlberg, but they could very well surprise us and produce a movie even worse than what we're imagining.
