I'll give you family guy, but american dad has been amazing. Episodes go in wild directions and it really seems like the writers have the freedom to be as creative as they want to be.
In all honesty, I'm not sure I've seen full episodes of american dad
I looked at their release date and bases on that I think what I saw (tried maybe like 5 episodes?) was family Guy. And since the other one has the same look and feel, I didn't bother to try.
But I'm pretty sure I catched snippets of it, and that didn't click with me.
I have the same reaction towards Rick and Morty. I saw another poster mentionned it and it made me realize this is also one of those show.
I dunno, to me it's like they try hard to be funny
Doctor Who. I haven't watched it since the Matt Smith doctor, but it was kinda surprising to me how massive it seemed to get in popular culture. Maybe it was just a Reddit bubble, but it seems like for a handful of years there was an intense fervor for Doctor Who. Tardis jokes, constant quotes from the show like the "bowties are cool" one, etc. etc.
It's a show that I remember as being decent with cheesy writing that was sometimes great, and some goofy special effects and CGI. While I enjoyed it, I didn't quite understand how it got so massive.
There's a little of 'instant nostalgia' with doctor who.
Apart from some really great episode, it's pretty sub par. Writing is usually not too good, suspense meh, lots of techno babble and random ways to solve a situation.
But it's also sweet, naive enough, and somehow I look back at episodes and overall plot with fondness. It also helps that the actors who played the doctors are all amazing imo
