This episode is clear evidence that The Simpsons - once the very best show on television - has way overstayed its welcome. Everything about it was awful. The gags fell flat; Homer as a grunge rocker (with a far bushier mop on his head than he ever had in the 1960s or 1970s) was mind-numbingly unfunny; the band Sadgasm was a stupid "spoof" of grunge; the use of the Verve's Bittersweet Symphony puts the action in 1997, a year when some of the best Simpsons episodes were actually made; the character Professor August adds nothing to the show and the subplot involving Marge attending university was pointless. Clearly, The Simpsons has been on television too long. Either it needs to go off the air or it needs fresh writers who can bring back the show's edgy 90s humor. Watching this episode reminds me of the bad old days when we were subjected to some of those later Happy Days episodes or reruns of Archie Bunker's Place or the final season of The Love Boat. Some critics were upset by the fact that "That 90's Show" more or less subverted the entire Simpson family history time line. For example, the episode invalidates just about all of the flashback episodes, including the classic "Homer's Barbershop Quartet," which was set in 1985 and showed Bart as a little kid. But this is not what offended me about the episode. It was tired. It lacked creativity. It didn't even have as much edge as your typical Suite Life of Zack and Cody episode. What a sad assessment of a show that in its heyday used to excite TV viewers so much with its splendid subversive humor.
