However, some people argue that the latest seasons aren't as good as the older ones. That's mostly a question of everybody's personal preferences. Just like any show, The Simpsons have both excellent, average, and bad episodes. Each season of the show contains episodes that got high ratings on IMDb and fans liked them.

11 Season 21: Treehouse Of Horror XX (7.3)

The Simpsons

The Treehouse Horror episodes are often well-rated because they're not only scary but present a new face of everyone's favorite heroes. This episode has three short stories, as the tradition is. The first one is about Lisa who wants to get revenge on her teacher, Miss Hoover, and makes a deal with Bart. The second story is about a zombie apocalypse in Springfield. The third, and final story, is about Homer getting his revenge on Moe for half-killing him. As usual for The Simpsons, the episode draws inspiration from other movies. This time, it's 28 Days Later (2002) and Alfred Hitchcock's movie Strangers On A Train (1951).

10 Season 22: Angry Dad: The Movie (7.1)

The Simpsons

This episode brings into focus Bart's previous creative work Angry Dad inspired by his real experiences with Homer. The Angry Dad character gets his own movie but when it becomes successful and starts winning awards, Homer wants success all for himself. Naturally, Bart isn't happy about it and conflict arises. The episode is one of the funniest ones of this season and it guest-stars multiple known actors, such as Ricky Gervais, Halle Berry, Nick Park, or Russell Brand.

9 Season 23: Holidays Of Future Passed (8.2)

The Simpsons

What will Bart's, Lisa's and Maggie's future be like? The fans of the show like to wonder about this. This episode does provide a possible answer. It takes place thirty years in the future and happens during Christmas. Bart and Lisa struggle to connect with their children. It shows that sometimes children can do the same parenting mistakes as their parents even when they mean well. An apple doesn't often fall too far away from the tree, but in this case, it makes the audience laugh.

8 Season 24: Treehouse Of Horror XXIII (7.2)

The Simpsons

Once again, the scary Halloween episode got the best rating on IMDb. It contains three stories, as is usual. In the first one, a black hole might swallow Springfield.  In the second story, Homer investigates strange occurrences happening in their house and he uploads them on camera. Finally, Bart travels back in time to 1974 and he has to fix things when something bad happens.

The episode pays homage to popular films such as Paranormal Activity or the Back To The Future trilogy but will interest any fan of the show.

7 Season 25: Brick Like Me (7.9)

The Simpsons

The 2014 animated Lego Movie is a popular film among both children and adults. This episode uses it as an inspiration source. A Lego version of Homer grows suspicious, he believes that the Lego world he lives in isn't real. He experiences a flashback to an alternate reality and wants to learn the truth. The creation of this episode took a long time, two whole years, but the result is well worth it. It combines two highly popular phenomenons - The Simpsons and Lego, and the combination works.

6 Season 26: Simpsorama (7.9)

The Simpsons

Even more popular crossover happened in this episode. The Planet Express crew (Leila, Fry, Bender, etc.) come back in time to stop the Simpson family from destroying the future. Matt Groening created both The Simpsons and Futurama. Many fans of both of the shows wondered what would it look like if the heroes of The Simpsons and Futurama met. This episode provided the answer to that, and it's just as epic as one could have imagined even though not all of the characters got the same amount of space.

5 Season 27: Barthood (8.4)

The Simpsons

The Simpson family is eternally young in the show, especially the children. But some episodes like to play with the idea of their future lives. Barthood is one of them, even though it primarily focuses on Bart and not all three siblings. Bart has a difficult relationship with his dad and sister because he feels like they overshadow him. It feels surprisingly real in the way it works with family relationships, and as a result, it presents a balanced mix of comedy and drama.

4 Season 28: The Town (7.1)

The Simpsons

This episode might not be interesting for everyone since it focuses on sports. However, it does give the Simpson family an opportunity to get out of Springfield for once and travel somewhere else. Homer takes them on a vacation to Boston when he learns that Bart supports a rival football team.

It's an unusual vacation, though, since Homer wants to prove to Bart that Boston doesn't deserve his support. As a result, it focuses more on their family relationships and less on the city itself, despite the episode's title.

3 Season 29: Flanders' Ladder (7.6)

The Simpsons

The Simpsons mostly stay down to Earth but it sometimes works with supernatural plots as well, and not just in the special Halloween episodes. In Flanders' Ladder, lightning strikes Bart, he falls into a coma and starts seeing ghosts. The show doesn't often deal with what happens to a person who's in a coma so the episode's plot feels like a breath of fresh air. As a result, it works as a good season finale since it's the last episode of the 29th season.

2 Season 30: Baby You Can't Drive My Car (7.0)

The Simpsons

This episode is the only one in the thirtieth season with a rating of 7 or higher. This might prove what some people believe - that the show isn't as good as it once was. Either way, Baby You Can't Drive My Car works. It tells the story of what happens when a self-driving car company arrives in Springfield and it steals all the employees from Mr. Burns' nuclear power plant. The story raises an interesting point in regards to collecting personal data and is both enjoyable and worth thinking about.

1 Season 31: The Way Of The Dog (7.4)

The Simpsons

The Simpsons tend to focus on human characters. As a result, this episode brings along something new. The Simpson family tries to discover what happened in Santa's Little Helper's past since he lashed out and bit Marge. The discovery is downright tragic. The episode is one of the few rare ones that aren't mostly about jokes but instead focuses on a character's development.
