Query: Yoga? Looks more like showga

Bought several of Yee's DVDs hoping they would be another great set of power yoga. After trying the workouts, must say I am disappointed.Yee's approach to yoga is more like Showga - lots of graceful acrobatic moves without a focus on yoga's core principals. In stretchy, show-all shorts that could only be meant to get dates, Yee blazes through ~20 poses per minute. Breathing - an foundational yogic element - is not mentioned in some of his videos. A couple of the poses, particularly the twisting back stretch, are so poorly instructed, I question whether they are safe for beginners. While Yee's form is good he fails to mention how to perform the stretches safely.Yee appears to be an excellent practitioner and is undeniably a yoga rockstar. But his videos ignore core yoga techniques essential for a beginner.
