It depends on the genre you're looking for, and if you're looking for something more adult oriented or family friendly. I really like Game of Thrones, Breaking Bad, Sons of Anarchy, Eastbound & Down, Justified, and Rescue Me for shows that are more adult oriented. For stuff that is more toned down, I like Burn Notice, Big Bang Theory, Young Sheldon, That 70's Show, and The Goldbergs.
If you're looking for animated stuff, Family Guy, Rick and Morty, South Park, Archer, Gravity Falls, The Simpsons, and the Venture Bros are all solid picks.
For anime, I like Outlaw Star, Star Blazers, and Naruto.
