I didn't expect much from this movie, I decided to watch because of a couple funny gifs I saw on Tumblr. I haven't seen much of McKinnon's work but after watching TSWDM I would gladly watch everything she stars in. I love her style of humor - quick, raunchy at times, honest. Maybe shes "a bit much" to some, but I really enjoy her silliness and the chemistry she and Kunis share. Two beautiful, funny, smart and completely relatable best friends getting into secret spy shenanigans in Europe? Sign me tf up. I've watched it twice and I'll more than likely watch again.
In conclusion, this film obviously isnt going to be everybody's cup of tea. But I personally laughed my a** off. To the low reviewers: watch without taking it so seriously and you might enjoy it too.
