I liked it better than the show because it went more in detail and could describe things the site couldn't or didn't have the time to. That being said, it's basically the same. If it weren't for the fact I could listen to it in about 11 hours, I would honestly not have bothered.
It could have been better
I really liked all the characters, well, they way they were developed and described. The good were good and decent, the bad were awful people. probably Aria Stark was my favorite all the way through followed by Tyrian Lanister and Rob Snow
The 'pirate voice' used for the characters was very distracting as it seemed more appropriate for a pirate story and not something Medieval based. When the same voice was used for so many characters it was even more odd. After a while it was so distracting I had to re-listen to parts because the voice was so annoying it stole my concentration and attention.
GRRM writes the best fantasy political drama around, and his characters are believable and you really start to care about them, which makes it all the worse when realistic consequences catch up to them to pay for their follies. Roy Dotrice does an excellent job narrating, though some of the pronunciation choices are a little strange. Either way, I definitely recommend this, especially if you liked the TV show. It has more drama and intrigue comparatively, and you get a much better idea of the characters thoughts and feelings.
