American Dad went from fantastic comedy to 'fuck it, nobody cares' shit. Before, American Dad had 'grounded' silliness. Shit that was whacky was explained. But now? Shit is just weird for the sake of it. Yes, there are good episodes every now and then, yes there are funny scenes every now and then... but the seasons are no longer 90% hits. They are 20% hits at best, 30% so-so and 50% shit. Tired flanderised characters, meta commentary instead of fixing problems (Stan commenting he never does CIA work any more haha if we point it out it is funny haha). But flat out weird shit isn't explained. Remember how Roger was meant to hide and he used disguises to get out of it... and Klaus was in doors? Remember when they gave up on this and people aren't freaked out by a talking fish? It's so fucking dumb. I know that isn't a post-Fox sale issue, but we have shit like Billy for no reason. Rogu for no reason. One episode we have 'Linda Memari is dead' and then a few episodes later she is alive.
Old characters are forgotten and replaced with new ones. Out of all the new characters, only Tuttle is worth anything and he isn't REALLY new. Rogu is shit. Billy + Doctor is shit. The weird product placement. The 'trying to be relevant' shit.
This is the same problem that Futurama suffered when it left FOX. Comedy Central just went 'lol whatever' and you have repeating episode plots, end of the world/universe shit multiple times a season, character reversals and dumb shit.
