Eager, but sensitive atheist medical student Alison Blanchard (a fine and sympathetic performance by fetching blonde Corri English) must overcome her own squeamishness about mortality while taking her gross anatomy class. Things get freaky when the unrestful spirit of the female cadaver she's supposed to dissect tries communicating with her from the beyond and starts committing a series of murders. Director/co-writer Jason Todd Ipson does an expert job of creating and sustaining a grim, intense and morbid atmosphere which becomes more increasing nightmarish and harrowing as the story unfolds. Moreover, Ipson keeps the tone relatively serious throughout; he never lets the plot get too silly or spoofy at any point. This film further benefits from uniformly sound acting from a capable cast: English truly impresses in the lead, plus there are excellent supporting contributions from Scot Davis as the nice, charming Brian Cross, Joshua Alba as the thoughtful, superstitious Carlos Aclar, Jay Jablonski as the brash, happy-go-lucky Rick O'Connor, Derrick O'Connor as stern, no-nonsense instructor Dr. Blackwell, and Reb Fleming as helpful psychiatrist Dr. Carolyn Saltz. The gruesome and convincing make-up f/x are guaranteed to make you squirm. Both Michael Fimognari's slick, shadowy cinematography and Michael Cohen's spooky'n'shuddery score further enhance the overall eerie and unnerving mood. A most effective and hence recommended shocker.
