History has greenlit its military-themed drama series Six for a second sesaon, the network said Thursday. 

The series, which follows a team of Navy Seals tasked with rescuing a fellow seal captured behind enemy lines, is averaging 2.9 million total viewers in Live+3 Nielsen ratings over its four weeks, making it the most watched new scripted series of the season, according to History.

The season one finale of the series debuts March 8. Six is produced by A+E Studios in association with Weinstein Television and created by William and David Broyles.

“Six is a captivating drama series that embraces our recent history, while being immensely relevant in the climate of today’s culture,” said Jana Bennett, president and general manager of History in a statement. “It has struck a genuine chord with our audience and we’re proud to continue to tell the courageous stories, both on and off the battlefield, of the complex lives of this elite military group.”

Six is a drama series with a solid premise, blending the working and personal lives of Navy SEAL team members: armed combat abroad; interpersonal and financial challenges at home. SEALs, we learn, are highly trained, though not immune to getting shot, and aren’t paid well enough to afford private school tuition or IVF treatments.

The cast is a good one, led by Walton Goggins (Justified), Barry Sloane (Saints & Strangers) and Kyle Schmid (Copper). Somehow it doesn’t quite gel, though, at least in the four episodes reviewed. The stateside family stories feel like they are tacked on and, of course, aren’t as compelling TV as a raid on Boko Haram or a firefight in Afghanistan.

A Homeland-lite secondary plot involving a radical Islamic (American) terrorist who wants revenge against Goggins’s character pops in and out. Goggins’s “Rip” Taggart, after washing out as a stressed-out SEAL, is put into a situation where he must summon up his best action hero moves and, we hope, rescue the innocent civilians and redeem himself as his former colleagues rush to his aid — if they can find him on time.

As with other History productions (see Roots, Vikings), the action does feel authentic and the Boko Haram aspect is interesting. It just doesn’t measure up to a full Six.
