The world is divided into two groups of TV viewers. Those who watch “Game of Thrones” and those who are all like, “Huh, what? Is that some kind of cheesy castles-and-dragons show?”

I was a member of the latter group. Then I previewed the April 1 premiere of season two (HBO, Sundays, 9 p.m.). Now I’ve switched sides. I pretty much love everything about this fantasy drama set in rival, cutthroat kingdoms.

I love the Emmy-winning performance by Peter Dinklage, above, as an intensely witty (and wittily intense) court adviser who kisses ladies on the cheek and cheekily tosses off clever dialogue. Lady: “I’m glad you’re not dead.” Dinklage: “Me, too. Death is so boring.”

I love learning “Game of Thrones” etiquette. A whiny young royal celebrates his “name day” by forcing wine through a giant funnel into a man’s throat. What a faux pas! His lady friend intervenes: “It’s bad luck to kill a man on your name day.”

And I love the lady who looks like Gwen Stefani on a bad hair day and has an awesome pet mini-dragon. She forcefully declaims: “No one will take my dragons!”

“Game,” you’ve got game!
