Porno is a funny and frightening time-machine trip worth taking.

For a film unafraid of occasional full frontal nudity, this is surprisingly puritanical, especially when you consider the plot.

Even if the sophomoric Porno doesn't make the grade, it represents a promising start for the talented filmmaker.

Theater employees will get a charge from the on-sire locations and the accuracy of working at a cinema, and there is some decent sex and violence, but ultimately, 'Porno' is a trifle.
