Interesting that Silent Running is list as "underrated", yet I think it's way overrated. I mean, on the topic of sci-fi, the movie has been mentioned in lists and otherwise for years. The theme is good, and I like the idea of watching the movie. But then I turn it on, and man, it's sure can be cringey. My shoulders go up around my ears when Dern's character is lecturing his shipmates on "real food". IRL, they would have thrown him out an airlock after one too many sanctimonious speeches. And that part with Joan Baez screeching on the soundtrack, ugh.
And to digress into nit-picking, Invasion of the Body Snatchers? Saw that in the theaters because...it got good reviews.
