There's plenty of history to be learned on Whitechapel, as the show goes to great lengths to have the various copycat killers replicate the murders of days of old with as much accuracy as possible. But the series isn't just for true crime enthusiasts who want to see some grisly deaths. The central trio of investigators — D.I. Joseph Chandler, Edward Buchan (Steve Pemberton), and Detective Sergeant Ray Miles (Phil Davis) — help hold the show together as they use brains, bravery, and dark humor to move the plot along from one season to the next. 

Since it's a British series along the lines of Sherlock and Broadchurch, there aren't very many episodes. The first two seasons have three episodes apiece, while seasons 3 and 4 each have six. Every installment runs for roughly 45 minutes, so it makes for a fairly quick watch. Given the mysterious nature of each season and how it switches to different killers, it's certainly enough to draw you in to the point at which you have to finish every season as soon as possible. Whitechapel was popular with critics when it was on the air, particularly when it came to the first season that was the most readily accessible for general audiences with its focus on such a prominent murderer like Jack the Ripper. Season 1 holds a 90% Fresh rating on Rotten Tomatoes. June Thomas of Slate wrote, "Accents, creepy historical crimes, that handsome English actor who always plays princes and posh boys... What's not to like?" 

Sadly, if you find yourself going through all four seasons quickly, there won't be any more Whitechapel coming down the pipeline. Rupert Penry-Jones took to Twitter back in 2013 to let fans know the series wasn't picked up for a fifth season. It may be over, but now that it's on HBO Max, a whole new crop of fans can discover it.
