If there is any movie that can be let down by mediocre acting or directing, then this is the one. Aside from Dylan Sprouse who gives an impressive rendition to his character of a social psychopath, the rest of the acting is a big let down.
The placid acting of the teacher played by Randall Park is no match for Dylan Sprouse who plays the student with much more credibility of a ruthless sociopath.
Many parts of the movie lack the necessary and essential direction that could have made this movie great. For example, the teacher not attempting to protect the family when in danger of such a predator.
The movie is only lifted by Dylan Sprouse's screen presence and I can see him to be appearing in bigger movies yet to come.
