It's my first time to make a review so bear with me on this one.
AOS is one of the kdrama that I got hyped watching. The first episode will always be the best episode of this series and is one of the reasons why I got into this series.

Story: This is one of those series that has the potential to be one of the best but ended up not living to its hype. I think the writers got influenced by the fans and didn't know how to continue the story later on.
So many questions left unanswered. So many plot mysteries that was left hanging - because the story started to focus on romance - almost each characters has romance shown in the series.

There are four young mages - yet, there was nothing for them to do - except to be part of love story.

The most disappointing is Jang Gang's return. He was the biggest mystery in this series but they made him come back just to die like that...

It would of been better if they announced that there will be season 3 - so the plots will be cleaned but they choose a rushed ending.

Cast: One of the best aspect of this drama is the casts. They all did a great job. The Somin did a great job portraying two different personalities - so it didn't take long for me to get use to her as new Naksu because her acting as Naksu was so close to the real one.
The rest of the casts did great job as well - even the extras.
