"Game of Thrones" season 1-4 review. SPOILERS

I've been watching HBO's "Game of Thrones" for quiet some time, and I can't wait for season five, which still seams so far away. Meanwhile, let me tell you what I thought of the first four seasons of this great show.
Season one really got me into it. It grabbed me early on, and did not let go until the very last episode. It has great character development and introduces us to the story beautifully. It sets up the world really well, and some interesting things happen. I just started reading the books, and season one is very close to the source material. Ned Stark's death is a huge turn at the end of the season which makes it impossible to not want to watch season two.
Season two was also very exciting.  Since Ned Stark is no longer around, this season allows other characters to step into the spotlight. The story focuses on Robb Stark and his mother, as they are fighting a war against the crown. I enjoyed watching the two families go against each other, however I do have a major complain about this season. It did not show any of the battles between the Starks and the Lanisters. I get why HBO did not show any of the battles - they would be very expensive to shoot, but I would still like to see more action and more of the actual war. Near the end of the season however, they do show us a great battle. I am talking about the battle of the Black Water, which was made pretty well. You could see that the creators were limited in their budget and CGI, but it was good enough and overall, I really enjoyed this season, not as much as the first one however.
The third season is most famous for "The Red Wedding". Once again, the main protagonist dies a horrible death. So does his mother and pregnant wife. I actually really liked the twist, and thought that it was done really well. Unfortunately, it was spoiled for me so I saw it coming, but it was still very impactful. Also in this season they introduce us to a new story line with Bran Stark. I thought that this was the weakest part of the season, and I did not enjoy their journey as much as I did the other stuff. This is also the season where Tyrion Lannister really shines. He became my favorite character, and he still is. The things going on with Daenerys are also really interesting, and I could't wait to see where she would be going in season four. Jon Snow has a pretty important story line in this season. He gets trapped by the wildlings and has to join their ranks. I really liked his story in season 3, and especially I enjoyed his relationship with Ygritte. I was excited to see how it would progress in future seasons.
Season four was by far my favorite one. A lot of very important things happen. In the very beginning of the season King Joffrey finally dies. It was really satisfying seeing this little sadist die in pain. He is a really awesome character that is hated by everyone who read the books or watched the show. However, Joffery's death gets Tyrion in trouble. Most of this season he is locked up awaiting for his trial. The dwarf gives an amazing speech and requests a trial by combat. The fight between the Mountain and Oberyn was really cool and gory, and I was shocked that Oberyn got killed, which means that Tyrion was going to be sentenced to death. However, Jamie helps him escape. During his escape Tyrion kills his father. I really liked the character of Tywin and I was actually surprised that he died. Another pleasant surprise was the battle on the wall. This was my favorite episode of the season, and it was really well made.
Overall, I've really enjoyed the first four seasons of this show, and I can't wait to see more.
