If you like a time travel show, I have 3 recs: Outlander (historical romance/drama, Netflix), Dr Who (you can watch all the modern dr who on HBO Max and then Disney+. The first season is a little bit of a 90s slog but gets so much better. Very heartfelt, campy, fun. Also some romance.) I recently watched Travelers on Netflix, it’s a lesser known show but did the opposite of Lost - it has a Great ending that makes you think back about the entire show.
