The entire concept of having a person's other personality kidnap teenage girls as a defense mechanism to traumatic moments from earlier in his life isn't only realistic, but it also takes advantage of advanced theoretical psychology concepts to create a movie that is both believable and terrifying, because it isn't that unrealistic to manage this type of incident occurring in real life. Secondly, because of all of the different personalities living inside Kevin's body, some of the interactions between his grown-up body and a teenage girl's one is quite creepy, and audiences begin to feel as worrisome as the girls on the big screen do.

James is able to truly transform into the incredible mind of Kevin and all of his different personalities living with inside of him, allowing him to capture the essence of so many different roles and bringing all into one. His performance is unforgettable and truly is able to make the movie that much more better, since it is able to elevate it to the next level, because he really sells the concept of having many different people living inside of one man's body, which adds to the movie's realisticness, making the movie that much more terrifying.
