Sword Art Online 2 : Redemption
The second season of Sword Art Online is redemption for the series. As much as I was critical of the first season, the second season greatly impressed me. The series continues its exploration of humanity living in a new online world, without stumbling into bad anime cliché.
To talk about the second season would be to ruin it. However, I finished the series with a tear, something very uncommon for me. Although I might not rate the series as high as classic such as Death Note or Fullmetal Alchemist, this is definitively a season to watch.
