As a squirrelly doctor at a Boston hospital who smells a rat when her best friend mysteriously goes into an anesthesia-related coma during a routine operation, Genevieve Bujold proves once again what a dynamic presence she is on the screen. Cool-headed one moment, hysterical and running-in-all-directions the next, she's instantly identifiable to us. As a mystery-thriller that is so filled with continuity errors, gaps in logic and a final act that gives the audience the satisfying release it needs but at the risk of all credibility, "Coma" shouldn't work (and, indeed, many fans of Robin Cook's wordy book didn't think it did). However, as a trashy, one-box-of-popcorn melodrama, the film is very enjoyable and suspenseful. Not the least of the reasons why it's so good is Bujold; handling herself like one of the best crime detectives ever concocted, she is gutsy, feisty, nosy and infectious. You never tire of her spirit. *** from ****
