The 100 (2014 - 2020) is a TV show that ran for 7 seasons - with a finale. The earth has had a global nuclear war and is believed to be uninhabitable by the survivors who have lived their entire lives aboard the Ark, a space station. An aging Ark forces the leaders to test the survivability of earth, by sending 100 young prisoners to the earth. The cast is great, but you can sense some inexperience with either the writing, the directing, or the acting in the earlier episodes, maybe all of the above. This show takes some patience, but the longer it runs the better it gets.

I've watched this show all the way through a few times. There are some seasons that are better than others, but the story evolves nicely as it goes along and the different settings of the seasons add some intrigue and mystery. It has some cool concepts, which are revealed over time (including time specifically in some cases). If you just read overviews of the seasons and episodes, they can seem sporadic, but everything does connect in one way or another. This is one of my favorite shows to watch, if I have to pick a show to re-watch. It has great music and the central characters are interesting enough to keep you watching. The finale is an actual finale too, which is rarer these days than it should be.
