Alright I guess... I live for the complexity and the insane depth of sound when listening to this kind of music. I didn't get it in this song for a long time.
Being entirely knew to this dubstep scene, I can't be a very accurate judge for others, but as music in general is concerned, I personally feel that the tempo increase has not been used to it's full potential. That is what gave you 4 stars.
Remember, don't go with beef franks; get summer sausages!
