Sorry to P!$$ on your parade, pal, but Moon wasn't THAT good. It was OK, but you think it was all that and a bag of chips??
**scratches head** I don't know about 2001 (hard to remember), but it certainly wasn't better than 2010, Alien, Aliens, etc.
It's not the intention of Sam Duncan Jones to try to have MOON be like 2001, but it was the inspiration, or part of it. MOON's premise is actually intelligently written with a lot of layers and in fact, it's one reason why I thought it had some slight tones to Tron: Legacy which I won't delve into the why so as to not spoil it to anyone reading here. lol.
However, the story was so good that I have to wonder what would've happened if Mr. Jones, son of David Bowie, were to write TRON? The outcome would be far different than the LOST boys' vision and much more fleshed out.
I've noticed some inspiration from OUTLAND (1982 film) in this one as well. It also reminded me a bit of SILENT RUNNING (1972) acted by Bruce Dern, one in which I suggest you check out. It's an old film, sure, but how they pulled off the production set was incredible in that the FX guy moved on to do the famous CLOSE ENCOUNTERS OF THE THIRD KIND.
The science portrayed in MOON was good and far more well grounded than what you would see in, say, Prometheus. It's funny because Gavin Rothery wrote a very scathing essay and blog about Ridley's latest film and how it fails on many fronts. That's when I realized that without him, MOON would've ended up as a crapfest. Duncan Jones was supposed to do a follow up sequel to MOON but for some reason, funding fell through and now he's going the route of doing a graphic novel based on the sequel. Not too different than what Darren Aronofsky did with The Fountain (both a film and graphic novel).
I've got a lot of respect for Rothery due to the fact they tried to go with the "hard" science fiction approach that has been lost for over 25 some years. The last "hard" sci fiction film Hollywood brought out was, I believe, ALIENS or ROBOCOP (Paul Verhoeven) in that vein. Gattaca, maybe?
MOON succeeds on a lot of things. It's definitely not on the level of Kubrick, but it comes pretty close.
