When Family Guy first came out I absolutely loved it, and I was pissed at Fox for never promoting it and airing it without telling anybody in like six episode runs every nine months.
When it was uncanceled I was excited as hell.
Then it turned out the show forgot why it was funny in the first place and turned every character that was originally good into something obnoxiously stupid and dickish.
Then it ran for several more years and spawned two awful spinoffs that were just as obnoxiously cheesy, stupid and dickish but without any funny characters.
Seth McFarlane is a proud purveyor of the comedy formula: If 60 year old Christians would hate it, it's automatically funny, even if you don't tell an actual joke.
