While many TV series are filmed in Canada, few shows are true Canadian icons in the same way that Murdoch Mysteries ​​​​​​is. Murdoch Mysteries has been on since 2008 and has maintained its dominance in the Canadian police procedural space. This is largely thanks to the fun it injects into its stories and characters and the ever-evolving cast of characters attracted to the series. Season 18 feels much the same as the show's early seasons, which is both a help and a hindrance. In the same way that Law & Order has been a mainstay for procedurals in New York, Murdoch Mysteries ​​​​​​has that same impact in Canada.

What helps to define Season 18 is the new energy brought in by renowned Canadian actor Paul Sun-Hyung Lee, best known for his work on Kim's Convenience and his many appearances in Star Wars as Carson Teva. He is the perfect new addition to join Murdoch and the other regular officers of Station House 4. Murdoch still manages to combine interesting cases, scientific evolution, and social issues in a way that is both fun and frustrating. Murdoch Mysteries is a comfortable show that audiences can watch for 1 episode or one hundred episodes with barely missing a beat.
