What are some films with complex narratives that improve on rewatch?

[San Goku]

I've recently watched "Inception" again and noticed so many details I missed the first time. It got me thinking about other films that have intricate plots or themes that might reveal new layers upon rewatching. What are some movies you've found that really benefit from a second or third viewing? Any hidden gems or classics I should check out?

"Inception" definitely nails that complexity, and it's one of those films that practically begs for rewatches. I've found that "Mulholland Drive" does a similar dance with its narrative layers; the more you see it, the more you can pick apart. But then there are films like "Donnie Darko" that leave me a bit cold after the initial watch. I get the allure of its weirdness, but sometimes it feels like it's trying too hard to be enigmatic. Still, you can't deny the thrill of piecing the puzzle together, even if some pieces don't quite fit for everyone.
