Still near the top of my list. I may look for different things to you guys in movies I see. I look for productions with an uncluttered style, made with finesse and without the need for huge casts and budgets - which is why I put this movie into the same class as THX-1138. Made cheaply in 3 months and with (realistically) one actor. A pretty damn brilliant result in my books. I don't think you can or should compare it to Star Wars, Aliens and all the other blockbusters you've mentioned. This is a movie you'd see at the Cannes festival, not the Oscars.
The thing about Silent running is one man's detemination although futile to ensure the survival of something that warrant's preserving despite all the cards being stacked against him
The robot in "Moon" reminded me somewhat of Huey, Duey and Lewie the only difference was that it spoke
