Crichton's excellent adaptation of Robin Cook's novel is one of the most intelligent sci-fi thrillers in years. A simple enough story, but one told in such chilling fashion that visitors to hospitals will never feel the same again.
Coma is an extremely entertaining suspense drama in the Hitchcock tradition. Robin Cook's novel is adapted by Crichton into a smartly paced tale which combines traditional Hitchcock elements with contemporary personal relationships.
Plausibility is not always important, but in a film as bereft of distinctive style and wit as Coma, it helps to believe in something. It can even help if one is offended. The aftereffect of Coma is a catlike yawn, benign and bored.
