The rest of the video is actually pretty good. And as said, the reaction in the beginning is totally understandable. But the way he narrated and presented the beginning part is not what I like. In one part he even zoomed in to the teeth part of the guy. Really, this looked like someone is angry at typical YouTube bullshit.

But, you know, I'm personally sassy like this too in forums. But I'm also not a leader of a project of this size. I really disliked that portion of first 4 minutes or so and even if its only that much, it sticks with me as first impression.
