Very interesting idea. The intro is a bit slow, and could use with a way to speed it up. When rating and commenting I like to go back through and double check things, so it was especially noticeable then, but even the first time through it felt a bit slow. I can see wanting to give the feel of waiting on a text to come in being the influence, but an option to click to advance would be great. Similarly, it would be nice if there was a speed adjustment for the video, or a way to move to/loop the part you are working on. Overall a neat idea, but the experience could be improved a bit with a few UI touches.
