Will (Hayden Christensen - American Heist) has done alright for himself since he left his home-town but decides to return their with his wife and their young son, Danny (Ty Shelton), when it becomes apparent his son is struggling and needs his father. But Will's plan to teach his son to hunt like his father did before him doesn't go as planned as Sheriff Howell (Bruce Willis - RED 2) warns them that there has been bank trouble in the area and they find themselves right bang in the middle of it when a man gets shot and a cop gets killed. With Danny being kidnapped, Will is forced to do what ever he thinks is right to save his son.
Let me start with one crucial aspect to "First Kill"; Bruce Willis does not have a lot of scenes and those he appears in are pretty terrible as he plays his character in the most dull, boring, dreary way you could imagine, to put it simply his character is lifeless. What does that mean? Well it means "First Kill" is mostly about Hayden Christensen as Will doing what ever he thinks is right to save his son, be it shooting men, lying to cops or ... well to be truthful the character of Will is not much better than the character of Sheriff Howell and certainly is as forgettable.
The trouble with "First Kill" is that it almost feels like someone tossed a few cliches together and said let's make a movie, but never fleshed it out to make it work. As such we have a father trying to save their son, good guys who are not so good and bad guys who end up not so bad. But it is all basic and when revelations, action and drama come there isn't enough detail to it to make it attention grabbing let alone attention keeping.
What this all boils down to is that "First Kill" is an incredibly ordinary movie which simply lacks detail to make it entertaining. Basically you might watch it once if you saw it on the TV schedule but you wouldn't feel a need to watch it again.
