2. Tyler Perry
As far as modern comedy movie enterprises go, the world that Tyler Perry has bestowed upon the planet is an abomination - the motion picture equivalent of a man dressed in a fat suit punching you square in the guts and stealing your wallet. Not only are each of his ventures into both the realms of comedy and drama tagged with a ridiculously self-righteous "Tyler Perry's" credit (as if the sheer mention of his name is actually warranted), almost everything the man creates is an insult to the intelligence of his audience. Because racial humour is important and it's definitely not something we should be steering clear of for political correctness' sake, but Perry's idea of racial exploration doesn't attach itself to any sense of integrity. As a comedy performer, Perry is probably best-known for his Madea character, a truly monstrous construction of stereotypical trash, and one of whom has been granted no less than six movies since her inception. And Perry's performance of Madea is just as terrible as you might expect: loud-mouthed, brutish and ashamedly aggressive, and lacking any nuance, skill or timing. Whether or not you agree or disagree as to whether Perry is funny or not, there's no doubt that this particular series of films (and Madea) are a genuine disservice to both comedy movies and, well, humankind itself.
