This passable British TV movie (shot on video) stars
Patrick Magee as a quirky psychology professor who invites three of his students (including the excellent
Joanna Pettet) to participate in a little extra-credit research project at his home one weekend. Unbeknownst to the hapless trio, the prof's planned behavior-modification experiments are designed to induce homicidal behavior in the subjects. Things turn out pretty much as planned, and the requisite killing spree begins. Not bad as made-for-TV thrillers go, this definitely benefits from an arch performance by the always-interesting Magee, but the cheap sets and the flat, washed-out videography may take their toll on the viewer's patience. ~ Cavett Binion, All Movie Guide
