Hard to Follow
I was interested in this video because I once took a Tai Chi class in college and was interested in starting back.
I found this video hard to follow. There are two styles used. In the first part, it is like a class. Scott talks to you directly and helps you through the moves. This was okay.
In the second part, Scott is narrating while he does a workout. This is where the real problem is. He tells you what he is doing AFTER he begins a new movement. His instruction lags behind the video, this causes the viewer to get confused.

Also, I was really put off by all the pseudo spiritual stuff. While I understand the concepts of Chi, I felt like he was getting real preachy.

I prefer to just get on with the form.
