Early Family Guy was fresh and hilarious back in 2000.
The shite it has become is not.
Yeah I was kidding. I didn't see a lot of Family Guy, but I do remember enjoying a few episodes of it in its very early days.
And yes, Rick and Morty takes a few episodes to get going. I must say I don't venerate it quite as much as others. The best of Rick and Morty is not necessarily better than the best of Community, so far. But it's way more imaginative. It's maybe the most imaginative show out there - better than the best of Futurama. But it's not got quite as much 'heart' as other shows, like Adventure Time.
