Both shows focus on cases that have occurred a few ages ago but have never been solved. Both have many cases that are solved throughout the show, with a main focal case in the background.

This is the first season of this show. The cases are showcased in both seasons very interestingly. Both seasons have many cases, each per episode which are always solved nicely.

Both actors are a part of this 2 Moons. If you feel incomplete after watching this, you might as well watch 2 Moons (although you may also be disappointed there.) Just watch the two act in the same screen space .
