I'm deeeeeefinitely the type of person who rewatches their favourite shows instead of watching new ones. I've got better at watching new movies, but with TV shows I still tend to stick to my favourites. I think it's a comfort thing tbh. But there are several shows that I consider to be my favourites and I've rewatched them qUITE a few times now.
Bones is top of the list, I think. I can't even really explain why. I just love the characters SO much and the dynamics between them and the plots. It makes me feel ALL THE THINGS and I've rewatched it at least 4 times, which is a lot considering there are 12 seasons.
Another favourite is
Brooklyn Nine-Nine. It makes me so happy. And at this point I have no idea how many times I've rewatched it.

I'm so sad it's ending but I have no doubt that it will feel complete when it does.
The last one I can think of off the top of my head is
The Good Place. I've only watched it through twice
so far but oh my gOODNESS, I love it so, so much. The characters. The humour. The depth. The lessons it teaches you. If you haven't watched it, I hiiiiiighly recommend it.
Other shows I enjoy: The Umbrella Academy, Death in Paradise, How I Met Your Mother, Lucifer, Chuck, Teen Wolf.
