HBO’s smashing fantasy epic “Game of Thrones” returns to TV in just under two weeks.

That’s a perfect amount of time to catch up. Here are 10 reasons why you should be watching.

1.Dragons!

Even those who don’t watch “Game of Thrones” probably know that it features dragons.

They start out small and adorable — they cook their own food with their fiery breath! — And later become the terrifying instruments of Dany’s (Emilia Clarke) liberation force.

Either way, they’re amazing. And you’ll probably find yourself wishing that they were real and that you owned one.

2.Stellar performances.

It’d be easy for “Game of Thrones” to become high camp. The show is set in a fictional world populated with dragons and witches and littered with made-up languages.

But nearly every performance on the show is pitch perfect and filled with true emotion. Despite the potentially silly fantasy trappings, “Game of Thrones” is always seriously great.

Case in point: star Emilia Clarke received an Emmy nomination in 2013 for an episode where most of her lines were in a made-up language.

Acting!

3.A fully-realized world.

“Game of Thrones” features a massive world, not unlike Tolkien’s Middle Earth.

The show has only explored two of its four continents — Westeros and Essos — but both are realized in breathtaking detail by the show’s masterful production design team.

4.Magic.

Besides the aforementioned dragons, “Game of Thrones” also features priestesses, giant wolves, “Walking Dead”-like zombies, and magical green fire.

The show overfloweth with enchantment.

5.Weddings!

So many weddings! Marriage is basically the currency of the realm on “Game of Thrones,” and that means lots of weddings.

So far there’s been one horrifyingly awkward one and one absolutely horrifying one. And season four promises a blowout for King Joffrey (Jack Gleeson) and Margaery Tyrell’s (Natalie Dormer) big day.

6.Surprisingly good child actors.

I have a theory that 90 percent of all child actors are terrible.

The child talent pool on “Game of Thrones” seems to be plucked from the other 10 percent.

The cast features numerous young characters, but performers Maisie Williams, Sophie Turner, Isaac Hempstead-Wright and Jack Gleeson are riveting in their roles.

They’re often as fascinating as the adults.

7.It’s based on a book series.

So if the show isn’t enough, you can always become obsessed with the books too.

8.The theme song.

Go look up “Game of Thrones theme song” on Youtube.

Listen to it.

Become inspired to trek over land and sea to bring honor to your family or whatever.

It’s great, isn’t it?

The best part is that it opens every episode.

9.Surprises.

Some are bigger than others, but nearly every episode of “Game of Thrones” features something that’ll make you do a double take.

Expect the unexpected, but also expect the stuff you wouldn’t expect in your wildest dreams.

10. It’s a pop culture phenomenon.

“Game of Thrones” finished its biggest season to date last year, and season four promises to be even bigger.

So hop on this faux-medieval bandwagon before it’s too late.

Season four of “Game of Thrones” premieres April 6 at 9/8C on HBO. Previous seasons are available on DVD, Blu-Ray, HBOGo, iTunes, Amazon and On Demand.
