One of my favorite works of science fiction is Back to the Future, and its various sequels. It may not immediately spring to mind when you think of science fiction, but it certainly ticks all the boxes. There's a kooky invention that defies the current laws of the universe, there is a mad scientist, and all sorts of goofs and gags ensue. I love a sci-fi movie that also has a rad musical number. It's a classic time travel movie, and honestly, I think we need more of those.
You know how everyone says they'd go to Woodstock if they had a time machine? What if there was a movie where that actually happened, and then you see 21st-century people navigating the realities of hippie culture in the 1960s? I'd watch the HECK out of that. But while we wait for that to be drafted and created, we have these sci-fi memes.
