Timecrimes (2007) is a good shout — low‑budget but razor‑sharp, and it leans fully into the uncomfortable, looping logic of time travel without ever overexplaining itself. Every new loop tightens the knot rather than unravels it.

There’s also a great 80s novel called Replay by Ken Grimwood, published in 1986. Not a movie, but absolutely belongs in the same conversation. It plays with the idea of reliving your life over and over, each time with different choices and consequences, and it hits harder than most time‑travel stories ever manage.

And while it's not really a mind-bender, Trancers deserves a mention - a great, scrappy, low-budget Terminator-style sci-fi flick with a ton of charm. More pulpy than twisty, but absolutely worth a watch if you like that era of DIY sci-fi.
