Its got a very good story and can be quite shocking and emotionally impacting (dat ending)
However often you get slumps where it can be quite boring, and most of the choices fail to have impact.
Hardly worth game of the year, shame it beat titles like Far Cry 3.
EDIT: I am a fan of the Walking Dead series as well, and actual gameplay wise I think Heavy Rain had better interactivity
If you are willing to play a game purely for the story and are satisfied with a point and click style of "interactive" gameplay go ahead.
