*******SPOILER ALERT******
This movie is light-hearted, but I couldn't stop thinking how Gary could so easily change from a pleasant, mild-mannered philosophy professor into so many different hit men (using wigs, rotten teeth and different personalities). All I kept thinking was, is he really a sociopath? Why was it so easy for him to stay in character as Ron, not to mention all the lying to the police? Maybe I've watched too many Law & Order: SVU episodes, but Gary was creepy to me. It was so easy for him to murder someone in cold blood. The woman he loves is just as bad.
I think a different script would have been much better. I was expecting a comedy, but this wasn't one.
