The Librarians, a four-season fantasy adventure series that aired on TNT between 2014 and 2018, is highlighted as an underappreciated option for fans of Doctor Who and Warehouse 13 who are seeking a similarly whimsical blend of mythology, magic and adventure. The show is a spin-off of TNT's Librarian TV-movie trilogy, which began in 2004 with The Librarian: Quest for the Spear starring Noah Wyle as Flynn Carsen, an adventurer tasked with protecting magical artefacts on behalf of a mystical Library.

In the series, Flynn recruits a new team of Librarians, Jacob Stone, Cassandra Cillian and Ezekiel Jones, guided by Guardian Eve Baird, to defend the world from resurgent magic after old adversaries the Serpent Brotherhood resurface. Operating from a Library annex in Portland, Oregon, the ensemble balances long-running storylines, such as battles with the Serpent Brotherhood and an Egyptian god of chaos, with inventive standalone episodes, including a Bruce Campbell appearance as Santa Claus and a Season 4 instalment that traps the cast inside various film genres.
