The show has been developing riveting crime drama storylines since 1999. While some fans prefer the earlier years of the show when Elliot Stabler was still around, you can't help but shriek with glee when it's on Tv. Despite the show's immense success after so many years, not all episodes were the best.

December Solstice (5.6)

To kick things off, the episode "December Solstice" in season 16 only received a 5.6 rating. The storyline focuses on an accusation of a celebrity author's wife was sexually abusing that turns into a legal welfare battle. Charmaine (Marcia Cross) has been secretly giving her husband erectile dysfunction pills.

When her husband, Walter Briggs (Robert Vaughn) is hospitalized due to a heart attack, Charmain forces him to leave to avoid any drug testing proving her secret. Barba pursues manslaughter charges after a second fatal heart attack. The episode had an intriguing storyline, but it sadly didn't have a high ranking according to IMDB.

Sanctuary (5.5)

Law & Order: SVU has done a good job over the years tackling current social issues, but the episode "Sanctuary" in season 18 didn't do so well. The team investigates a hate crime against a Muslim family who were assaulted in their restaurant. When their main suspect is released, the team is caught between the victims and the suspect's family.

While the episode created a tense situation for Benson, who has to make a tough decision on who to arrest without being seen as the villain, it only got a 5.5 rating from IMDb.

American Dream (5.4)

This leads to Barba having to drop the charges that lead to a divide within the community. The episode tackled a serious issue in today's society, which was highly praised by some reviews. Others felt as though the episode was too forceful in its approach with its message.

Granting Immunity (5.4)

Many fans of the show would remember this specific case in the episode "Granting Immunity" in season 16. By this point, Benson is a loving mother to a young boy named Noah. When pornographic photos of a young girl go viral at her high school after a sex party, the team is called in to investigate.

Heightened Emotions (5.2)

There were certain elements in the episode that some fans felt were a little weak. The episode involved an Olympic pole vaulter who was living a double life. She was found by police disoriented and bleeding from her assault. As the team investigates, their victim's story becomes shaky and unreliable as they discover an underlying mental illness.

Some viewers felt that while the main storyline of the case was intriguing, it was a bit weak when it came to the script. Another aspect fans didn't care much for was the story between Amanda and her sister Kim, who was just released from prison on parole.

Depravity Standard (5.2)

Some fans would remember this episode for its different storyline. In the episode, "Depravity Standard" some audiences felt as though the story had it's mediocre moments that dragged on. The episode revisits a case from three years ago when Benson investigates a suspect, Lewis Hodda (Tome Sizemore).

He is connected to a new case, but when the boy's parents refuse to let him testify, Barba must revisit the 1999 case of the murder of Hector Ramirez. Benson's interrogation tacts are questioned during her interview on the Ramirez case.

Meanwhile, Benson revisits her experience with Lewis and will be the deciding factor in the case.

Intimidation Game (3.3)

The lowest ranking in the 21 seasons of the show is the episode, "Intimidation Game" in season 16. It's hard to believe that Law & Order: SVU could have a storyline with such a low rating. The story was inspired by real-life events of the Gamergate controversy. Game developer Raina Punjabi (Mouzam Makkar) is being targeted by online predators who believe women don't belong in gaming.

With the oncoming release of her game, one of her employees is assaulted at a convention that becomes the interest of the SVU team. It soon escalates as Raina dismisses all safety precautions set by SVU and becomes an even bigger target. Reviews on IMDb felt the episode took too many wrong turns with its central theme. Reviews also criticized the writing of the episode that was overdramatized and made characters out to be more comical than criminals.
