Regarding Solaris - I thought as a SciFi drama it was well done. However I couldn’t get past the fact the authors\movie writers thought the sun was like a stove whose pilot light had gone out. All they had to do was flip a thermonuclear Bic and restart it. i.e gather up all the earth’s fissionable material and make a “BIG BOMB”!
Wasn’t that Sunshine?
I liked the conclusion where one of the last surviving characters touched the surface of the sun. Pretty neat.
