Adam Sandler is such a terrible actor that it ruins the entire movie. He always speaks in voices that make him unbelievable as a real person. I find it incredible that an actor that has been in as many movies as he has still can't act in a manner that makes him believable in his role. This movie would have been so much better if they would have cast anyone else because that dude is just not funny. Aniston and Sandler were completely unbelievable as a married couple and their characters were not smart enough to have been able to solve the case. Last Sandler movie I will ever give the benefit of the doubt.
