Hilarious, relatable, heart wrenching and adventurous. It’s one of the few shows that can pull off almost any kind of episode concept; Such as Groundhog Day, Scooby Doo crossovers, or playing their actors. It can seamlessly break the 4th wall and each character is 3 dimensional. It is able to reinvent itself without having to change the central characters.
You can also skip plenty of episodes/seasons and still be immersed in the show (if you think 15 seasons if a tad much)
I’d recommend if you like:
-Good Omens
-X-Files
-Stranger Things
-anything apocalyptic
-friends
-bones
-Lucifer
-The Originals
