Vampires from space, basically. There is a bit more to it than that though. There's an anti-war message, some nice special effects and a collection of routine characters on a downed plane (business man, doctor, mad bomber, physicist, pilot, stewardess, assassin, etc.) pitched into a disastrous situation who try to work out how to get out of it, initally squabbling but later being distracted by aforementioned vampires. There isn't much blood to be seen as the vampires are neat suckers. The cast are adequate, no one standing out. There are some good (the blob entering the crack in the forehead) and bad bits (the constantly convenient falling rocks) in the movie which is a shame. The ending was downbeat but confusing. How were all the people killed? Who killed them? How were they killed so quickly? It had some good ideas but the execution of them failed mostly.
