I am the first person to comment on this film, and it is a very deep film with Student Cole Hurley (Micah Alberti) versus Sociopath Teacher Kay Weller (Marina Black). Ms. Weller is one of the most disgusting cold-blooded women you will ever find in a motion picture. She is also extraordinarily dangerous, because she can get not one but two cops (one of each gender), to do exactly what she wants them, which is murder her husband, and frame Cole for the crime. What is real bad is although her husband is wealthy, her real goal is not money, it is she wants by learning their weaknesses to basically prove how intellectually superior she is to everyone, and how she can manipulate anyone into doing whatever she wants (Cole above all (except Cole has a conscious which is one mistake). Spoilers ahead: Another problem is Cole learned his lessons all too well, and decides to play Detective and finds out she is using him (and everyone around her), and sleeping with both cops, and he records everything and captures her. The film ends with him finishing up a college paper and mailing it to Weller in prison. It was noted by Cole's roommate that they (not Cole alone) will become a millionaire off of it (of course, he will not fall for that), and since Weller was not angry and was reading it, you can tell she is working on it with him. My gut feeling is Cole made her that offer, so that in exchange for her help writing this, she will see her theories on Behavioral Science live on, and despite being in prison, she gets to fill her massive ego (which is her weakness). As for Cole, he gets the Credit (the title "Xtra Credit"), the money and the hot chick Lexy (she makes you think of SEXY and not by accident) 8 of 10 stars.
