There's a bizarre human appetite for that which is awful. From lookie-looing at traffic accidents to Man Show mooks to Lettreman's stupid pet tricks to worst home videos, etc., people like to watch people being stupid, outrageous, and ridiculous. Therein lies the appeal of "Turbulence", a not-to-be-taken-seriously white knuckle ride into the realm of the ridiculous with Holly as the "Stew" who's got to save a 747 jumbo jet with a handful of passengers against all odds including one very whacked out serial killer (Liotta). Ok, ok...this movie is stupid. However, for those who can get to that place in their heads where they don't intellectualize, just go with it, and enjoy the humor-tinged hair raising suspense and silliness, 100 minutes of entertainment awaits.
