We could be here all day. Started early reading it and with classics, Jules Verne and H G Wells, Azimov, Clarke, on to Clifford D. Simak, Robert Heinlein, Ursula Le Guin, Kate Wilhelm.
When in my teens there was a woman, Judith Merrill who edited a an anthology of Short Science Fiction stories from around the world for some 8 years. Introduced me to the style/skills of people i hadn't heard of before. And can't forget Harlan Ellison as both writer and editor (Dangerous Visions anthologies).
Of course i watched Twilight Zone and Outer limits faithfully, later the X-Files. Huge fan of Star Trek 'Universe', they've done it so well while minding continuity and honoring their beginnings.
I've talked elsewhere on SF about having watched a lot of old 'B' movies that were SciFi. One of my favorites was 'The Day the Earth Stood Still'. Unlike a lot of people i liked the remake too, thought they did a good job of updating for today's world. Actually bought boxed set DVD with both versions and special features.
I enjoy both serious and comic SciFi. The comic ones often sneak in even more thought provoking questions than the serious ones, which are often too focused on a single scenario, concept. The Men In Black franchise actually threw in same microcosm/macrocosm concept that was in book/movie Contact, by Carl Sagan.
SciFi allows people to consider sociopolitical questions in disguise-in ways that bypass people's defensiveness about their biases even tho with some the point too obvious from the start.
