As usual people start bitching about "skill", when the point of making the video is to be entertaining (it was).
So what if he can take projectiles like the Terminator & missed a few blocks?  It was fun to watch, especially that first section where he took a weed-whacker to the enemy team. 
Also I personally prefer seeing full rounds from a player instead of a 'kill vid' with lots of editing.  You can get a sense of how someone plays differently from you.
