Query: Disappointing

The box claims this video is appropriate for intermediate to advanced yoga practicioners. It is wrong! I was extremely disapointed. The video is, in fact, more appropriate for not-quite beginners. I was so irritated that the video didn't live up to its claims that I took it back to the store and demanded a refund. (I got it!)
