I want to start it. But is it really interesting in the beginning of the show?
I need to watch this show.
Watch it. Mother and I began it recently and thoroughly enjoyed it. The first season does have a slow start,kicks off around episode four, and the first season it is a set up to the entire series because it evolves drastically after the introduction that is season one, but since you can binge it now, all shall be well. Ten episodes a season is very easy to watch. You will thoroughly enjoy it, I promise.
Hard to say a number one favorite as there are so many I enjoy, but I would say Renly. I feel as if it's between Renly, Arya, Jon, Theon and Robb. I also really like Jaime, Varys, Jorah, Tyrion, Dany, and Littlefinger. Mother also has a huge variety of favorites. It is truly hard to pick a favorite and it will be different any day, but today I say Renly.
Least favorite is easy. It's Frey, Craster, and Trant. Luckily, two of those have been...dealt with accordingly.
