Unscrewed

An often genuinely funny mockumentary.

Produced for peanuts (and looks it), but offers enough laughs to please even those who don't usually venture into downtown art houses.

This is first-rate comedy of discomfort, so don't sample it with a date unless you're looking for a very queasy evening.

Even if actorliness sometimes invades the tired faux-doc form, Unscrewed is, in the end, a likable, wrinkly taint of a movie.

If Ms. Smith's and Mr. Hoffman's mopey, sheepish performances are quite convincing and ultimately sad, the movie constructed around them doesn't really know what it wants to say or how to say it.
