This is an excellent action-comedy about a professional hit-man who builds a romantic relationship with his former prom date while visiting his hometown on a mission to assassinate an important person. It is a bit tame for an R rating, it contains occasional strong language and infrequent but strong violence, though not overly so. I'm mature (not to brag) and I first watched it at 9 but for average kids, 13 and up is definitely OK.
