Its a good book in general. Its a long read cause its very descriptive which is part of its charm. It doesn't just tell the story, it makes you see/imagine the surroundings/scene and what people look like. 
 These books are divided into POV characters so if you like the characters, you'll definitely enjoy them. But if you don't, some can feel quite pointless. I skim through Dany's chapters cause I find her story boring *sorry!*. I love Bran but his first few chapters were annoying. However if you really think about it his actions make sense. He's a child after all, so I guess I should give him some slack. 
 There's a lot more "action" in Tyrion's chapters. I enjoyed it a lot! (view spoiler)[...Except when the story almost always ends up with Shae. Argh I DO NOT LIKE THAT GIRL. (hide spoiler)] 
 All in all its a really enjoyable read :)
