Some sci-fi movies don’t just bend your brain – they try to fold it into origami. The films on this list crank up the concepts, stack timelines, invent rules, then dare you to keep up, sometimes at the cost of clarity (or basic human sleep).
That doesn’t mean they’re bad. In fact, plenty of these complicated sci-fi movies are ambitious, fascinating, and weirdly rewatchable – just also the kind of “What did I just watch?” experiences that can feel like they went a step beyond bold and straight into overcomplicated.
