I started watching it but I've only seen the first episode, I missed the one on Sunday. I wasn't aware they were based on a book, if I like the series then I'll pick up the books
You people who haven't read the series but are watching the show are making me cringe.

The show is doing a good job but NO show can hold up to the integrity of a book, especially the way those books are. You REALLY should stop watching the show and at least get through the book before resuming.
I hope they are easy reads....lol Or I don't know how I'll get through them all.
They are not hard to read... but they are hard to swallow. Martin kills off characters left and right, with sometimes jarring effects. When I read the first book and they pushed Bran out the window I was so jarred by it that I read like 4 pages of the next chapter before realizing I wasn't taking in a single word because I was still in shock.
(Yes, that's a spoiler but it's freakin' chapter 2... get over it.)
