It's a movie about a guy who has grown cynical from years of anti-fascist action, though he's bit tsundere about his allegiance. In the end he chooses to bear the jealousy over his lover and abandon his life of convenience and comfort to fight for what's ultimately right.
It's a movie that resonates all these decades later, forgoing easy answers for a real stance. And it's amazingly quotable.
Ya know what? Sure. This website has plenty of posts complaining about AI already. This is now a Casablanca appreciation thread.
I also think it's a great movie which holds up spectacularly well. Despite my efforts, I struggle to appreciate many "classic" films (Vertigo is overrated, and I will die on that hill). However, Casablanca is just perfect. It's a compelling concept, turned into a tight script, and performed by skilled actors. It really is an all-time classic, and I recommend it to everyone.
