I found Season 2 to be entertaining, though also disappointing given my expectations as a fan of the books. On a scale of 1 to 10, it's a 6. Maybe a 6.5 at best.
I understand why screenplays often deviate from the source material - it's more engaging and adds some mystery when you aren't certain how events are going to unfold. However, in this case, I don't think they did a particularly good job. Also, most shows of this nature rarely have the staying power to make it past 4 or 5 seasons, so I suspect they're planning to shorten the storyline significantly and that means major plot deviations.
