Yeeee-Haa!
I have seen it argued that most American Movies are cowboy movies in disguise; that Hollywood is so in love with it's only truly original creation that it keeps reinventing the cowboy myth. I'm not sure I totally buy that argument but Slipstream is evidence in support of the theory; it's a cowboy movie with aeroplanes.
Actually it goes one better than that. It's a Spagetti Western with aeroplanes! Substitute the planes with horses, make the android a priest and this movie would be indistinguishable from any one of a dozen Italian Spanish semi-arty "shoot-'em-ups with pretensions" of the Seventies.
The film isn't as BAD as I had been lead to believe by some of the reviews I had read here but it certainly wasn't good.
