I'm relatively new to the show since I started watching every episode when they had the prime time condensed reruns.
They need Seth back, but I guess with his schedule even Weekend Update is probably too much, even he didn't write that. He wouldn't have to do any writing.
I quickly realized Bill Hader was the best cast member they had and he's gone. Later I realized Fred Armisen was second. Vanessa Bayer, Aidy Bryant and Bobby Moynihan are the best people they've got now. Kenan is pretty good too.
I'm sure it's not what it was in the Dan Aykroyd/John Belushi era, but it's not that bad.
