I had to stop watching. I like you bro, otherwise I wouldn't even bother to respond. I read a lot of your stuff so I know you got something to say, I just didn't much care for this video. My critic:

1. script way to fast for just about everything on screen but definitly the longer stuff. I would consider removing anything text longer then 2 sentences for sure. This is a survey video correct? The point would be to "introduce" the subject to the knowledge "not" teach them everything there is to know about the subject.

2. the music is annoying. I have suspected for a long time you a hippie type and that music proves it! Ditch it.

3. video is too long, without scope, and needs to be condensed refined.
