Does anybody think that Cleveland Jr. is the most three-dimensional Seth MacFarlane character of all time? The two I can compare him to is Brian and Stan Smith, which both are deeply developed characters, but it's only been 12 episodes and we've learned so much about Cleveland Jr. it's insane. This show is amazingly character-driven and plot-driven at the same time.
The writing sparkles because it puts character humor first before wacky, nonsensical humor. Take for example, the song that Cleveland Jr. sings. It is both funny for being edgy but it also tells us about his character so much and his reasons for falling in love with "Tyra": her personality and their shared interests, not for her looks. This is the kind of writing the Simpsons would strive for back in the 90's (though still, that show was smarter)...
I also had a huge laugh at Cleveland getting high and getting the idea for the Roller Coaster (aka the Cider Slider aka the Brew-Choo Train), that was great.
Props to Mike Henry once again...
