This episode had some of the funniest moments of the season, and the gags coupled with a focused and well-paced story made for a solid episode. I've never seen The Departed, so a few of my complaints about the show may be premature (the predictable nature of Donny saving the day, Ralph's final line, which everyone who's seen the movie seems to love), but there were some gags that fell rather flat either way. Specifically, Lisa kicking Bart in the face with cleats was odd, and some of the car lot scenes dragged. One gag in particular strikes me as particularly gross--were the hillbillies who planned to buy Homer's car really going to do what I think they were?
On the plus side, good one-time character, good story, good gags. The breach of trust reminded me of Three Men and a Comic Book, and we even got a nice screw-the-audience joke as well ("Donny...grab Milhouse's legs"). All in all, very well done down-to-earth episode, with good music and art direction to boot.
Nice to see a good showing that doesn't bend the rules of The Simpsons. 4/5 B+
