Weirdly I have made less progress on my SF viewing goals than my reading goals. The collection of Quatermass films I got on Blu-Ray turned out to be Region 2 (England), so my player will not play them! A friend is converting them for me.
I did rewatch Aliens and Prometheus. I love the Alien franchise. I even love the ones that people say suck.
There are a number of SF films on Netflix that I have not seen, as well as Amazon Prime, so I will likely delve into those in the coming weeks.
