The best show I have seen on AMC since Mad Men and Breaking Bad. There are some differences between the book (one of the best books I have ever read, by Dan Simmons), and the series, but not enough to put me off at all. Great performances and writing. The only thing I would change would be to keep the creature invisible or barely visible; the CGI didn't really hold up for me there, but still the series is fantastic, and it is so beautifully shot even though it was filmed mostly on a soundstage. I thought this was a miniseries, and when I found out there would be a season 2 I was a bit skeptical, but seeing how the first season ended I will be back!
