Duncan Jones' Moon has received a fair amount of praise as a (rare) serious science-fiction film, and I went in hoping for a visually stunning mindfuck (given the fact that all reviews reference 2001 and the thing is directed, after all, by David Bowie's son!). And it's a pretty good film, all things considered, with a nice look for its low-budget, a creepy and claustrophobic vibe, and a strong performance(s) by the almost always interesting Sam Rockwell. But it proved to be a little plot-heavy for my taste, struggling to explain away its weirdness instead of just relaxing and reveling in it.
With its eerie computer voice (the soothing sounds of Mr. Kevin Spacey), I suppose 2001 is the obvious touchstone for Moon ("Open the pod bay door, HAL!"). And there's a little Blade Runner and Solaris tossed in for good measure (although I have to admit not having seen the Tarkoskvy original, only Soderbergh's remake). Moon never feels totally original in the way that it should, but at the same time it accomplishes certain things very well, primarily in capturing a really stifling and spooky combination of the loneliness and timelessness of space, which would almost certainly unravel many of us, much less a sole guy on a three year contract in a lunar mining outpost.
Worth a look!
