What's your favourite series

Supernatural still my favorite series of all time.
I used to like The walking dead too, but, stoped watching some time ago and when I was back, i've had forget most of the history and gave up of it.
I really like some series like "How to Sell Drugs Online (Fast)", Nanatsu no Taizai (Seven deadly Sins), Rick and Morty, and many others.
Currently watching Ratchet and Outsider, and loving both.
