Most of you already watch the series or at least you have seen them around. It's actually impossible to miss them. They are everywhere. Anyway, i haven't read the books (neither i'm planning to) so the review it has no comparison with them.
Every episode it's like watching a movie. They are over 50 mins sometimes reaching 1+ hours. Special effects, music, acting, places...are all magnificent. You barely say that those are tv series and not a high budget movie. Well, don't imagine LOTR but you can see how much effort has been put in.
They say the series are for everyone. I say they are not. Not because it's fantasy. This has nothing to do with it actually. It's more of what it is as a story. If expect action, there is no much. Everything is political with backstabbing and lies and things like that. It barely has battle scenes of any kind. So people who are used to those things, might get bored after 5-6 episodes. The story is intriguing with mystery and such.
If you are bad names, you will also have problem. I'm good with names and i barely remember half the characters. They are way TOO many. I was annoyed by that. Why they have to be so many anyway?
Another big one is the sexual content. True Blood is nothing compare to it. Too much info people! They need to cut some! I forwarded all the sex scenes and they were many. Some didn't even make sense. Why when there is a character's monologue you need at the background two girls having sex? And he was talking and talking...i skipped the whole thing and i don't even know what the guy was telling and if it was important.
There is violence. Towards animals, people and whatever exist. There are some really bloody scenes.
Some of the relationships between the characters are disturbing (no i can't accept sister and brother having sex or later with her cousin or whatever the guy was).
Seems like it's full of negatives. It's not. It's a nice world, with nice ideas (it also has dragons) about people and their traditions but at some points it was overdone (either cause of the story or cause of the producers).
The cast is nicely picked. With Sean Bean one of my favorites.
The show has such big audience that signed for 2nd season after the 1st or 2nd episode.
Worth mentioning: The opening. It's one of the most beautiful openings i've ever seen.
