1) She's super SUPER funny- I feel like this goes without saying... But Melissa McCarthy is one of the funniest human beings on the planet... If not the funniest dare I say it. She was amazing in bridesmaids, and although I didn't think she was the "scene stealer" that she was dubbed in that movie (only because I thought everyone was absolutely AMAZING in bridesmaids) she has been the absolute funniest person in ever in many movie roles and she is just perfect. 2) She makes unlikable roles really likable and easy to relate to- Her characters are always super odd and usually quite hard to relate to. Tammy isn't someone you would necessarily want to hang out with in real life, but I feel like Melissa McCarthy made her so likable and easy to relate to that she had a depth other actresses wouldn't have brought to her. Another great example is her character in Identity Thief. Why should we like that girl at all? She's a criminal, she steals Jason Bateman'...
