If you're an HBO subscriber — if you've got the streaming service HBO Go — you can catch up on the partially made-in-Utah "WestWorld."

(If you're an adult, that is. The show is very violent, and there's a lot of nudity as well.)

After a slow start, the "WestWorld" plot permutations are fascinating. Just don't be surprised if you're left thinking, "What just happened?"

And if you figure it all out, please let us know.

Binge-watching the 10-episode Season 1 also is a chance to try to pick out where in Utah the series filmed. Among the sites:

• Castle Valley

• Fisher Valley

• Dead Horse Point State Park

• SR 128 (just south of Arches National Park)

• Kane Creek Road (east of Moab)

• Onion Creek (east of Arches National Park)

(That's according to the Utah Film Commission.)

"WestWorld" was only partly filmed in the Beehive State. Season 1 also took the cast and crew to several California locations, including European Street and Mexican Street on the Universal Studios backlot; the Pacific Design Center in West Hollywood; the Paramount Ranch in Agoura; the Melody Ranch in Santa Clarita; the Fillmore and Western Railway in Ventura County; and the Vasquez Rocks Natural Area Park in Agua Dulce.

By the way, HBO has ordered a second season of "WestWorld" — but it probably won't air until sometime in 2018.
