One of the main reasons to watch this film is to see just how amazingly aesthetic David Bowie used to be, and this film, filmed midway through his decadent and powder nosed 'snow white tan' 70s phase when he made all his best music, captures him both at the finest and worst moments of his youth, and nobody could have played a better alien!

Also, a pretty good film just by itself, although, no, I don't quite get the 'deep' ending either, but that's a very 60/70s movie trait right there, when the film makers realised their core audience would probably be on more drugs than the cast, I mean, have you seen 2001!?
