i rewatched season 3 a couple weeks back and i think it's pretty consistent with the quality of the other ones. there was a LOT of meta stuff like introducing a perfect female character commenting on the show, a lot of comments about the show coming to an end. the whole season felt like the end and it worked in this kinda bittersweet way i think. it had heart.
what i want is more equality with the episodes. since season 2 there have been less and less huey and more and more riley/granddad.
