I can say with 100% certainty that this show is legit! I've never played the games or the read the books but I throughly enjoyed this series. I see a lot of people comparing it to Game of Thrones & while I haven't even watched that entire series I have watched all of season 1 & I'll say that they are very different shows. Sure they're both fantasy epics & share 2 actors from both shows but the world, rules, beliefs, & everything else are completely different in their own right. Give it a chance watch the first episode as that should be enough to give you a feel if you'll like the show or not. A heads up though you must pay very close attention to everything happening on screen as the show doesnt hold your hand & explain everything outright & leaves it up to you to fill in the gaps which I personally enjoy because to many movies & shows feel the need to dump continuous exposition on you (the show even pokes fun at that in one episode). All in all I very much enjoyed this show, the production is high quality, the actors make every line of dialogue believable, the story is enticing with a lot of lore behind it & am very excited for the 2nd season. Even considering picking up the books or video games!
