Rebecca,
Great news! I've been watching since the beginning,since I've read all the books before it was made into a TV series and wasn't crazy about the actual filming and direction, but each season got better, as the show got more money and better writers,etc.
Another great show, under the radar of most people, is "Vikings" on the History channel:

Again, give the first season a little break, until you get grabbed by it. After the first season, it's really good!
