With NCIS returning for its 22nd season on October 14, 2024, it’s worth wondering if the show has already reached its pinnacle or has yet to hit its ceiling. Of course, with Leroy Jethro Gibbs (Mark Harmon) no longer leading the investigative team following his departure in 2021, it will be difficult for the long-running series to recapture past glory. Speaking of the past, 2024 marks the 20th anniversary of NCIS Season 2, arguably considered the finest chapter in show history.
