The plot is that of 1,000 other films: a group of twenty-somethings on the way somewhere (a marriage) get lost and end up spending the night at a B&D in the middle of nowhere when the shit hits the fan and the blood blows fountains. Suddenly the "dead" walk and the last survivors take retreat in the boarded-up B&D as the dead shuffle and dance their way to the final showdown... Of course, a lot more stuff does happen, but watch the film to find out what.
In regard to the oddly familiar faces that populate the flick, the group of twenty-somethings do rather a lot with the little that roles like this tend to have. (David Carradine has a short guest appearance as the owner of the B&D, but his casting is less good than mandatory.) Oz Perkins is properly strange both before and after his transformation – as might be expected from a guy who not only had his acting debut as the child Norman Bates in Psycho II (1983 / trailer) but is actually a son of that great weirdo Anthony Perkins. Jeremy Sisto (May 2002 / trailer) is laid back like always – at least until he loses his head, after which he becomes a rather funny guy. Ever Carradine does a fine job as the babe-with-balls, Erik Palladino manages to make his asshole of a character become likeable and even gets the most laughs in variety of his scenes... hell, everyone does good in the film. About the only thing that grows old rather quick is the country-singing narrator who really should've remained a one-or-two-scene joke instead of a running gag.
On a whole, self-referential zombie-Hicksville comedy went further and was done better two years later in Slither (2006 / trailer), but Slither obviously had a larger budget than this labor of love, and even if Slither has a lot more zombies and goo, it doesn't bathe in the cheap gore to the hilarious excesses of this Dead & Breakfast.
