10 Reasons Family Guy Is The Laziest Show On Television
9. The Characters Are Beyond Inconsistent
It's hard for an audience to get invested in a cast of characters when even the writers can't seem to decide who said characters are supposed to be.
In addition to being irritatingly one-dimensional, none of the characters in Family Guy, main or otherwise, have any sort of unique identity, modus operandi, or moral code. In fact, they're not even so much characters as they are living plot devices.
Their actions are unpredictable because they don't have any personalities to adhere to, they just do whatever it is the plot demands of them for whatever story is currently being told. Then, every single week, it resets and the process repeats itself.
Any one of the characters could learn a valuable lesson in one episode, realizing they need to change their ways or do something differently, then immediately forget it by the next episode and never speak of it again.
When you're not going to put any sort of effort in developing distinguished identities for each character and are just going to turn them into something different week after week, why would you expect anyone watching to care about them in the slightest?
