1. Love Isn't The Greatest Force In The Universe
If there's a moment that Interstellar jumps the shark, it's when Anne Hathaway's Brand - previously a totally rational, almost uncaring genius scientist - reveals her romantic weakness for one of the lost astronauts the crew is hoping to track down, leading to a rambling monologue about how love is the most powerful and unquantifiable force in the universe. What's even worse is that, by the time of the film's climax, she's proven to be right: somehow, Cooper's love for his daughter Murph is what helps him return to her in the tesseract, and get the message out about leaving Earth. Yeah, no, that's not science even in the slightest. That's the worst kind of Hollywood cliché being shoved into what's otherwise film that trades on hard science, abandoning that intellectual edge in favour of indulging in the idiotic trope that love conquers all. That's silly. Love is nice, obviously, but it isn't some great, unknowable cosmic force, like a nice Chutlhu. Love is mysterious, but there's plenty of stuff in science and biology that's mysterious, and romantic. Love is almost certainly just the firing of chemicals in human brains to kick start reproduction vital to continuing the species. Powerful, but not universe-shaking.
