It was an enjoyable film, though I don’t anticipate revisiting it, and I would suggest others check it out. The movie brought to mind "Bounty Hunter," yet also incorporated aspects of "Guest House" and "The Hustle." I found the depiction of a sociopath's psychology quite unsettling within this kind of film, but it does offer a detailed look at having one’s identity taken over and the kinds of people who engage in such actions. Jason Bateman and Melissa McCarthy are both excellent comedic performers; however, certain moments felt overly theatrical even for them. There were times when watching it felt like an extended "SNL" bit where individuals would ask if something would be humorous, and someone would invariably say, “Yes, include that, just to see what happens.” It wasn’t bad by any means, but there was potential for it to have been truly exceptional.
