My review will be the shortest i've ever written, as i dropped this drama and still don't understand how it could get such a good rating. I started this title because of all the hype around it. It disappointed me in everything; Characters are all exaggerated, sense of humour that isn't funny, lack of acting .... etc, etc.
The ratings on MDL aren't fair and most of them are probably for Yang Yang only. The title got hyped because of the novel/animation and Yang Yang. If it was for another actor, i believe ratings will be less biased.
To me this drama isn't worth the hype nor your time. If you want to watch King's avatar story, watch the animation.

If you want to watch a c-drama about gamers and romance, i'd recommend you to watch Falling Into Your Smile - it is another caliber !
