While you're not likely to run across Girlfriend from Hell at the Cineplex, the film is ideal fare for the video-store "hot 'n' spicy" shelves and such cable TV moviefests as Up all Night. The title character, played by Liane Curtis, suffers from intense shyness. She'd do anything to be popular--even sell her soul to the Devil. His Satanic Majesty pops up on cue, and soon Curtis is fawned over by everything in pants. But the devil never does anything for free, so you can be sure that Curtis' attractiveness will get her into very hot water.
