I watched Moon last night.
I loved the set for the moon base, very 2001: A Space Odyssey / Alien / Star Wars IV and I thought Kevin Spacey as the robot was a stroke of genius.
However, I saw through the plot pretty quickly and it ultimately became predictable. I did like some of the editing though. There's a scene where the guy is freaking out, running around the base and all of the cuts reminded me of the section of 'Eternal Sunshine' where Carrey and Winslet are rushing through Carrey's old memories.
I'd give it 7/10
