Through 14 seasons, Criminal Minds has delivered some of the most twisted and shocking serial killer cases to ever hit television. The show, though, is not just about the FBI solving crimes, catching serial killers, and saving lives. This is a show that remained fully invested in the lives of its characters and the mental stress that working a job like this can place on someone.
From the start with Gideon and Hotchner leading the BAU with Prentice, Spencer, and Derek to the additions of JJ, Rossi, and Ashley, plus the always delightful Penelope Garcia, the character moments are what made the show so popular for so many years. With season 15 promising to mark the end, here is a look at the best episodes from the first 14 seasons of Criminal Minds.
10 The Replicator (S8E24)
The main villain of the eighth season of Criminal Minds was none other than Mark Hamill who portrayed John Curtis, also known as The Replicator. He was an interesting villain since he was a former FBI special agent with a genius-level IQ who turned into a serial killer. In season 8, he started to create copycat crimes of cases the BAU solved in the past.
There have been few deaths of the main Criminal Minds characters, but that changed in the episode "The Replicator" when Curtis killed BAU Section Chief Erin Strauss as revenge when he was left to take the blame on an older case. This season finale featured a huge loss, a great climactic scene, and it was a perfect goodbye for the season.
9 Minimal Loss (S4E3)
"Minimal Loss" was just the third episode of the fourth season of Criminal Minds, but it ended up being very important, and it even played a big role in arguably one of the best episodes of the entire series with "300" over 10 years later. The episode pulled its inspiration from the 1993 Waco standoff with David Koresh.
Luke Perry starred in the episode as Benjamin Cyrus, the leader of a cult who goes on the defensive when the FBI comes in to investigate claims of child abuse at the compound. The episode saw Prentiss and Reid captured inside the compound when a gun battle begins between law enforcement and the cult members, and the end is twisted when the victims take the side of Cyrus in the fight.
8 Mayhem (S4E1)
"Mayhem" is the season 4 premiere as the BAU investigate the bombing of an SUV in New York City that was carrying a member of the team. This explosion happened in the season 3 finale, so it had a lot to live up to since fans had to wait till season 4 to learn if someone they loved died. It lived up to expectations, and no more.
This episode was not so much of a search and rescue as it was a nail-biting thriller, with Hotch and NY special agent Kate Joiner forced to keep first responders away after they were injured in the bombing because the attackers targeted first responders. This also started a level of tension between Hotch and Derek that opened the season on a very high note.
7 Penelope (S3E9)
"Penelope" was a hard watch because possibly the most beloved character on Criminal Minds, Garcia, fought for her life after she was the target of the new unsub. It was sad and horrifying since she was the one who sees the good in people, and it was her happiness at going out on a date only to end up shot by a serial killer that hurt her almost as much as the injuries that almost took her life. Everyone who watches Criminal Minds knows the close brother-sister styled relationship between Derek and Garcia, so watching him try to contain his fury as he hunted down the unsub was great.
6 Damaged (S3E14)
"Damaged" is a Rossi-centric episode and follows him as he sets out to finally solve a case that haunted him for 20 years. Someone killed a couple, leaving their three children without parents, and the murder went unsolved for two decades. Through the years, Rossi continued to check in on the kids and made sure they had everything they needed.
It was the regret from this unsolved case that brought Rossi back to the BAU to begin with. In this episode, the team is called in to investigate a similar case, and Rossi eventually gets a lead to his cold case. He then sadly learns his years of assistance has continuously reminded the kids of their parents' unsolved murder. In a truly touching moment, Rossi finally captures the killer and lets the kids know so they can finally have closure.
5 300 (S14E1)
10 years after the BAU stopped a cult leader named Benjamin Cyrus, his followers returned for revenge in the 300th Criminal Minds episode. They now followed a new cult leader named Benjamin David Merna who restarted it with one of Cyrus' wives. He was also known as The Strangler—a serial killer with 299 victims.
In this episode, The Believers kidnap Reid and Garcia, and this is made even worse when the cult actually has members within the FBI. The plan was for Reid to be the 300th victim to make a point. As a 300th episode, this had it all, from callbacks to the previous 299 episodes to a mystery that had its origins over 10 years before.
4 Revelations (S2E15)
Spencer Reid is one of the most interesting characters on Criminal Minds, a brilliant young man who has trouble dealing with his own insecurities and whose own mother is institutionalized for paranoid schizophrenia. Much of his neuroses are explored in "Revelations" in season 2 when he is captured by split personality serial killer Tobias Hankel.
The BAU frantically tries to find Reid when a live feed of Hankel abusing the agent airs. Meanwhile, Reid is drugged and is flashing back to his childhood. This episode saw Reid forced to kill his captor, knowing that inside the multiple personalities was someone who needed help and this changed him for a long time.
3 The Fisher King (S2E1)
The Fisher King was a two-part case, the season finale of season 1 and the season premiere of season 2. The case surrounded a man named Randall Garner who was badly burned in a fire that took almost his entire family and ended up institutionalized at the same asylum that housed Reid's mother Diana. Despite his clear mental illness, he was released and set his sights on Reid and his partners in the BAU. Through season 1, he stalks the BAU members and then starts to torment them. This ends with him shooting Elle as a season-ending cliffhanger. Elle lives, and it is Reid who finally finds Garner, who can only watch as the killer blows himself up.
2 100 (S5E9)
The most demented, dangerous and hated villain in Criminal Minds history is easily The Reaper. Portrayed by C. Thomas Howell, had killed 20 people and was the unsub on the first ever case that Hotch worked as a BAU senior. No leads came, and The Reaper stopped killing. 11 years later, the lead investigator in the case called Hotch and said that he was dying and believed The Reaper would start killing again. It was true.
Through season 4 and 5, The Reaper made Hotch's life a living hell. This started in "Omnivore" and launched one of the biggest and best cases in Criminal Minds history. It ended in "100" and resulted in one of the most horrifying moments in the show's history when the team had to answer for Hotch killing The Reaper after he murdered his ex-wife Haley.
1 Masterpiece (S4E8)
Jason Alexander turned in one of the most chilling and despicable villains in Criminal Minds history. He was Henry Grace, a narcissistic serial killer who believed he was born to be a master killer. Rossi captured his brother William, another serial killer, and this ruined Henry's life, which made Rossi someone he wanted to destroy and "Masterpiece" gave him the chance.
He admits to killing seven missing women the BAU had been hunting and that there were five others, including three children, that would die if they didn't find them and one would die every two hours if they didn't. The thrilling conclusion saw Rossi interrogating Henry and hearing in horror that his entire BAU team died in a trap Henry laid. However, the twist was they knew what he was doing and saved everyone with no casualties, and Rossi chillingly tells Henry he will be there when they execute him for the other murders.
