Emma Stone's performance
was pretty bad.
It was so bad I really started questioning her acting ability, so I looked at her filmography and noticed I preferred her performances in comedies like Easy A, Crazy, Stupid Love, and Zombieland. She has a breezy, sweet charm that's endearing and very watchable. As for the dramas, I thought she was good in The Help and Birdman (even though I could barely watch that movie).
In this movie she was just awful. She was stiff and awkward and her angry scenes were hysterically bad, stomping around like a little kid - really over-dramatic when she didn't need to be.
I like her so I'm going to give her the benefit of the doubt. She realized right away she was in a *beep* movie and decided to ham it up and just enjoy her time in Hawaii. I hope.
