It seems like the suburban American location that this movie is set in has been plagued by a rash of kidnapping young girls who are later found chopped up and tossed in various dumpsters across town. The killer is Otis (Bostin Christopher); he kidnaps girls and apparently reenacts strange high school prom fantasies involving some girl named Kim (which he insists on calling his victims, not matter what their real name is).
The Lawson family is your pretty typical group of suburbanites. The parents, Will (Daniel Stern) and Kate (Illeana Douglas), live comfortably, and have a pair of standard teenagers in Riley (Ashley Johnson) and Reed (Jared Kusnitz). Riley is your typical straight A student, who is daddy's little girl and gets away with pretty much anything, much to Reed's chagrin as he is constantly be punished.
When the family orders pizza from a different delivery company than normal, Otis (who works as a pizza delivery man) meets Riley and starts obsessing over her because of the slightest bit of kindness she shows. It isn't long before he makes her his next victim, and the family finds themselves waiting by the phone with Agent Hotchkiss (Jere Burns), an FBI agent who has been working on the case since the beginning.
While following Riley's imprisonment, we learn that Otis is basically a screw up, at least in the eyes of his brother, Elmo (Kevin Pollak), and Otis seems to want nothing more than to be Elmo. That's why the sick fantasy he keeps trying to reenact is an imitation of Elmo's senior year of high school where he goes to the prom with his now-wife. While the first half of the film definitely hits on the demented, dark humor that makes Otis strangely amusing, the real fun doesn't start until Riley gets free and calls her family, who go to Otis' house seeking revenge.
What is really both surprising and disturbing about the Blu-ray release of Otis is the complete lack of special features. I mean, even the DVD release had a commentary and a couple of other features. I just can't figure out what kind of excuse there is for not providing a little something extra, especially in this day and age, and especially on Blu-ray. While Otis is a great and disturbing film, and I highly recommend seeing it, if you are at all interested in special features, then the higher visual quality afforded to you by the Blu-ray disc isn't enough - you should pick up the DVD version.
