In no particular order:
- Back to the Future: One of the few filmic takes on the genre that does a reasonably good job of being self-consistent with respect to causality, while still having nods to stepping on butterflies (e. g. Twin Pines Mall→Lone Pine Mall).
- Primer has an obligatory place on this list.
- Red Dwarf has, for all that it's a sitcom first and SF second, some excellent takes on time travel sprinkled throughout its run.
- Bill and Ted's Excellent Adventure, once you get past all the farcical bits, has some excellent "this is a time travel story" beats. "Remember to set this Deus ex Machina up later on so that we get out of this tight spot we're in right now."
- Arrival has a great closed information temporal loop.
- Babylon Five has some really good long-form temporal hijinks.
