The show is fine, but books are fantastic.
The casting was really great, but overall the show had the feel of a cheaper SyFy channel show and not an HBO quality show.
I know SyFy doesn’t have the same budget as HBO. I know that science fiction isn’t cheap either.
For me personally, the low budget SyFy shows are fine, but for mainstream America,it’s not going to break through that way.
PS: if you haven’t read the books, I highly recommend it. It’s my favorite series.
