Sometimes a television series will begin and, despite my interest in it, it completely falls off my radar before I have the chance to watch it.

“The Librarians”“The Librarians” — a TNT series currently in its fourth season — is one such show.

It seems like the announcement of the series was just yesterday.

My interest in “The Librarians” began with the trio of movies that were released in the early 2000s, featuring Noah Wyle.

This trio of movies — “Quest for the Spear,” “Return to King Solomon’s Mines” and “The Curse of the Judas Chalice” — were released in 2004, 2006 and 2008.

Wyle, fresh off of his time on “ER,” portrays the clumsy somewhat goofy, perpetual college student Flynn Carsen.

The three films chronicle his struggle to find the way as the lone Librarian, a guardian of a mystical Library housing magical artifacts.

The TV show has brought a change in how the Librarian system works.

There now are three Librarians — we’ll say in training — each possessing different qualities necessary to carry out the mission of the Library successfully, a mission that has the librarians saving the world from evil by using their intellect. Carsen occasionally drops in to assist them.

Overall, the Librarian franchise can be a bit campy, but there’s something familiar about the dynamics of the show. At first, I had a hard time putting my finger on what it could be. In fact, I got a few episodes into the first season, which began in 2014, before I made the connection.

Given its searches for mystical or magical objects and the call to save the world over and over again, the show began to remind me of “Warehouse 13,” which ran from 2009 to 2014 and fell in the gap between the three Librarian movies and the TV show.

The actors who have appeared on the show have been mainstays in other works.

For example, Christian Kane was in “Angel” and “Leverage,” John Larroquette was a staple on “Night Court,” Rebecca Romijn was a regular on “Ugly Betty” and the original Mystique in the “X-Men” movies, and Matt Frewer — who appears in the first season — was a regular on “Eureka.”

Overall, both “Warehouse 13” and “The Librarians” are somewhat of guilty pleasures.

Neither are educational — or always funny — or particularly rooted in action.

But they mostly are family-friendly and generally an easy way to entertain a brain for 40 minutes.

“The Librarians” is a series that I would categorize as a good binge-watching show — for lazy-day weekends that are too hot, too rainy or too cold for any outdoor activities.
