Hilariously bad! It's a bit like a film has been made of a Viz magazine cartoon strip. It zips along at a fair old rate, so you certainly can't say it's boring. I especially loved the bits where the plane was rocking/turbulent, and the actors were chucking themselves about in their seats to simulate this. Don't miss the compulsory vomit in a bag scene. I was convinced the 'co pilot' has charcoaled in his 5 o clock shadow too - take a look, no ones top lip is that dark, surely. I began to wish, though, this had been done as one of the 'Airplane' films, because the script would have been just perfect for the franchise. It just needed a Captain Over....
