Tv show: Tripped a great watch, low-ish budget but very well done. Starts off as kind of a stoner comedy but gets way deeper, while still being fun. Also it’s more of a dimension travel show rather than time travel.
Movie: Primer a pretty smart movie, I think the directors (who also starred) were scientists so the story is quite grounded in how time travel would (likely) work out.
Movie: Time Lapse a gripping movie about a camera that can show the future, mostly filmed in one house. A good watch.
