Chuck (2007-12). It's a niche cult show and a great love story with a great cast that has fantastic chemistry together (and had a lot of fun filming the show). It's also deeper than it looks, with two parallel bildungsromane (growth journeys) for Chuck and Sarah that take all five seasons to complete, an ethical exploration of love vs duty (from Star Warrs applied to the spy world) and utilitarian ethics vs virtue ethics, and a very nice and satisfyingly deep but still fun exploration of real vs cover (real identity or relationhsip vs cover identity or relationship), a ton of pop culture references, a fantastic sound track that understores and enriches the story, and a very clever chiastic narrative structure with parallels, counterpoints, and mirrors between scenes, episodes, and seasons. (You have to do some spy work to figure out what's going on with these spies, which led to unending discussions and arguments among fans in Internet boards when the show came out.) You may not catch any of the deep stuff above (I didn't) and will simply enjoy the unreal chemistry between Chuck and Sarah and their story. It should be free on Amazon Prime. Lois and Clark (1993-97) is basically like Chuck but easier to understand. It was free on Tubi until a few months ago (it might come back). If you are into Korean drama, Crash Landing on You (2021) is a great one-season overview of the relationship between North Korea and South Korea, symbolized through a beautiful and pure love story between a stoic North Korean soldier and a bubbly South Korean businesswoman. The main actors got married in real life after this show. The show was a sensation when it came out a few years ago. Can be korny (Korean corny) at times, but a great story nonetheless.
