Bad Brooklyn Nine-Nine episodes are usually few and far between. Like every TV series - specifically sitcoms - the beloved detective comedy doesn't have a clean record of flawless episodes. In Brooklyn Nine-Nine's case, the majority of the episodes tend to be very meaningful, hilarious, and heartfelt.

But then you have filler episodes and those that just didn't end up looking as good on screen as they might have looked on paper. Some of the episodes on this list had forgettable plots - or stories that did nothing to advance the plots, some just weren't as good as others, and some simply failed to jive with audiences.

Let's take a look through the 10 worst episodes of Brooklyn Nine-Nine, according to IMDb.

10. THE EBONY FALCON (SEASON 1, EPISODE 14) 7.7/10

This episode is named after a nickname that the Nine-Nine gang gave Terry; the Ebony Falcon. It's not that this season 1 episode didn't have several hilarious moments. For example, The Ebony Falcon's cold open is probably the most memorable in Brooklyn Nine-Nine history; featuring the gang playing "Wife Or Dog", a game where they literally guess whether Scully's talking about his wife or dog when referring to a "Kelly".

The episode is not bad by any means, and it features several interesting and hilarious subplots. It's impressive for a first-season episode, but it took place at a time where everyone was still finding their footing in the show.

9. SAL'S PIZZA (SEASON 1, EPISODE 9) 7.7/10

Stephanie Beatriz and Andy Samberg in Brooklyn Nine-Nine

Sal's Pizza was a season 1 episode that featured veteran sitcom actor Patton Oswalt in a guest role as Fire Marshall Boone. Virtually all procedural shows have a common problem and that is repetitiveness. When every episode is basically the detectives solving a new crime, the series gets tedious fast and the writing starts to feel too formulaic.

Luckily, in later seasons, Brooklyn Nine-Nine broke the mold more and more with fresh ideas and intriguing storylines. But before that, the procedural format got boring from time to time.

8. FOUR MOVEMENTS (SEASON 6, EPISODE 4) 7.6/10

With season 6 being Chelsea Perretti's final season as a series regular, Brooklyn Nine-Nine had to give the beloved Gina Linetti a worthy, ceremonious, spectacular sendoff. Gina herself is a gimmick, but no character is one-dimensional in Brooklyn Nine-Nine. Everyone is fleshed out and developed to the point where the audience feels close to the characters and their relationships with each other.

Brooklyn Nine-Nine has never been a show to shy away from conveying heartfelt emotion and poignant moments. The series does not try to laugh off important moments, and it knows when to choose sincerity over comedy, vice versa, and even how to tastefully combine the two. Four Movements may have received a lower rating due to its lack of plot progression, but it ultimately delivers in the character development department.

7. RETURN TO SKYFIRE (SEASON 5, EPISODE 8) 7.6/10

The character of DC Parlov - Terry's favorite author - only appeared in two episodes, but the storyline that involved him actually felt really draggy. Sure, it was entertaining at first to see Terry fanboy and eventually recruit Jake to The Skyfire Cycle fan club. A storyline with DC Parlov already took place in season 4, and no one was really that thrilled to see the character return in season 5.

Return To Skyfire does have its share of redeeming moments, though; such as Jake, Terry, and Rosa dressing up in Skyfire cosplay to attend Legend Con.

6. CAPTAIN LATVIA (SEASON 4, EPISODE 10) 7.6/10

Storylines involving Charles' son, Nikolaj, are fun in small doses but get old fast when they are overdone. Captain Latvia's entire premise revolved around Charles enlisting the rest of the Nine-Nine to help him track down a toy that Nikolaj wants for Christmas.

Since this episode heavily featured Charles' son - as well as his wife, Genevieve - it was eccentric and a little over the top, even by Brooklyn Nine-Nine's standard. Stories involving Nikolaj's time in the Latvian orphanage are plentiful, and although this episode features a good amount of bonding time for Jake and Charles, Captain Latvia fails to captivate.

5. THE NIGHT SHIFT (SEASON 4, EPISODE 4) 7.6/10

After Captain Holt and Jake had been stuck in Florida for three episodes, they finally returned home to Brooklyn and the Nine-Nine family in The Night Shift. As the title alludes to, this episode revolves around the Nine-Nine gang struggling to survive life on the night shift.

If anything, the low rating for this episode is most likely due to the fact that it was featured a crossover with New Girl. Zooey Deschanel guest-starred as her character Jess Day, so understandably this episode of Brooklyn Nine-Nine felt a little different.

4. THE SLUMP (SEASON 1, EPISODE 3) 7.6/10

The Slump was the third episode of Brooklyn Nine-Nine's first season, and since pilot seasons are notoriously hard to pull off, the low rating for this episode is understandable. The Slump was not a bad episode, though; being the first season, the characters were simply underdeveloped and had not yet found their signature quirks and charm.

The Slump revolves around Jake having a notable collection of unsolved cases on his hands. He desperately tries to close the cases, and meanwhile, Holt recruits Amy to lead the Junior Police Program For At-Risk Youth.

3. THE TAGGER (SEASON 1, EPISODE 2) 7.6/10

Jake and Amy shake hands in front of Terry and Boyle in Brooklyn Nine-Nine.

The Tagger was the second episode ever of Brooklyn Nine-Nine, and it focused on one of the most important dynamics of the series: Jake and Holt. Jake shows up late to work and Holt - already sick of his immature behavior - takes it upon himself to punish him.

Things feel new, different, and most just underdeveloped in this episode. The pilot episode of Brooklyn Nine-Nine was, of course, a hard act to follow, but one thing The Tagger had going for it was the introduction of Jake's desk mouse, Algernon.

2. HE SAID, SHE SAID (SEASON 6, EPISODE 8) 7.3/10

Brooklyn Nine-Nine is certainly no stranger to covering social issues as well as controversial political issues. One of the things that makes this series unique is that it always handles said issues in a tasteful way, all the while maintaining its beloved quirky sense of humor.

He Said, She Said was a poignant episode that covered a heavy, dark topic: sexual harassment. The episode revolved around Amy's experience with this and was referred to as the #MeToo episode.

1. RETURN OF THE KING (SEASON 6, EPISODE 15) 6.6/10

Gina Rodriguez Terry Crews and Stephanie Beatriz in Brooklyn Nine-Nine

It seems a little harsh that Melissa Fumero's directorial debut in Brooklyn Nine-Nine ended up being the lowest-rated episode of the series on IMDb, but that's certainly not all on her. Return Of The King is basically just all about Gina's return and what her eccentric life has been like since she left the Nine-Nine.

This episode didn't have a lot going for it, plot-wise, and the one-episode return of Gina seemed a little unnecessary since her departure took place only a few episodes ago.
