To get straight to the point, this series had a ton of potential and I really really like the idea of being trapped in a game. A big problem was that there is little character development. Another point I really did not like that the first half of the series was great, but when they suddenly and unexpected beat the game we are left with another 11 episodes of lame story line.
Honestly if you watch the first 14 episodes of SAO you can stop at that point. If I had then I would probable have given this series another point or two overall.
