Bart Gets a 'Z' is a good episode of season 21. I can't believe this episode was actually good!! Most Simpsons fans say that Season 11 is where the Simpsons became bad, and then once the modern age came along it became even worse. Well this is when the modern age starts, Season 21. So far Season 21 has been as good as Season 20. In fact, the first two episodes of this season ( Homer the Whopper, Bart Gets a 'Z' ) are better than the first two episodes of season 20 ( Sex, Pies, and Idiot Scrapes, Lost Horizon ). And I actually like Season 20. I would consider it the 3rd best season in the middle age ( Season 11-20) after Season 12 and 15. I expected this episode to be okay, and it exceeded my expectations!! The next episode doesn't look that good, but I'm happy to have one really good episode and one good episode before it. The thing that makes this episode so good isn't the humor. It's the depth. It might just be me, but I feel like there hasn't been an Edna Krabopil episode in a long time. The last Mrs. Krabopil episode I remember was called My Big Fat Geek Wedding, and it was the last episode of Season 15. To me, this episode gave Edna even more depth than in the awesome Season 3 episode Bart the Lover ( My favorite Krabopil episode ). This episode shows me why Edna is so depressed and also gives a realistic view on depression. Edna feel like a real person and not just a cartoon character who was made 21 years ago. I wish more episodes had the amount of depth this episode had. Besides the drunk line joke, this episode didn't have much humor. It wasn't unfunny, it just didn't have a lot of jokes. I love how this episode gives lots of depth to Bart too. Bart always had a lot of depth, but I liked how they made a layered story about Bart too. Even the new "cool" teacher had a little depth. That guy probably struggles with teaching kids, so he just gives up and doesn't. If this episode had depth and sharp humor too, I would probably rank this like 8.6 out of 10. Since this episode doesn't have that sharp humor, I would rank it a 7.4 out of 10, which is what my final score is. Even though it doesn't look good I'm excited to watch the next episode of the season, The Great Wife Hope. I'll make sure to post my review on here in about 4 days at least. I can't wait to see if the next episode is really going to be bad.
