Family Guy was pretty good until like season...5 or 6. Afterwards it just became too dependent on the cutaway stuff and it felt unnecessarily cruel often. But not funny. Granted, I haven't watched the recent seasons, but I started to dislike it around season 7 I think.
Honestly I prefer American Dad, but again, haven't seen recent seasons.
It won't be Silver Surfer, it'll be another herald of Galactus who is a woman.
