I find Melissa McCarthy absolutely hysterical. She is a lock for the top five funniest people in my opinion. It really doesn't matter what she is doing. Her delivery and physical humor get me every time. This movie is a pretty great testament to this. Spade a spade - it was a pretty pointless and stupid movie. But the surroundings are carried by the aforementioned strengths of McCarthy and I still found it enjoyable and funny. It is nowhere near the league of The Heat or Identity Thief where the movie around McCarthy was also hysterical. This is just a testament to how talented she is when it comes to hitting the funny bone.
I would still recommend this movie to anyone that is also a fan of Melissa McCarthy like I am. I honestly wouldn't recommend it to anyone that isn't though because if you don't find her funny - the movie is pretty much trash.
