I love Omega, Westworld and Soylent, I'd put Silent Running up there with them as well. Never saw God Told Me To (although I had planned to use that line in my defence if I was ever arrested).Omega Man is fantastic.
I also watched Criterion Collection sci fi over the break. But I chose:
Westworld -- I love this movie. Hadn't seen it in a while. Yul Brynner as the gunslinger was so out of left field, but it worked. he did great.
Soylent Green -- I've seen this many times too, but this viewing was a little more poignant for me.
God Told Me To -- First viewing of this. Interesting movie. The up close and personal views of va jay jays was unexpected and a little surprising given the year it was made -- 1976.
And Deborah Raffin is as hairy as a damn howler monkey. Wow. Her arms were so friggin' hairy, I was like, girlfriend, shave that sh*t.
