Query: I've seen better

I've been doing yoga DVD's for almost two years, about 2x/week on average. I went from unable to stretch at all to almost a full russian split, and very flexible & loose compared to most people. I love the the Ultimate Stretch Workout with Ana Brett & Ravi Singh which is also a thorough workout but was fun and left me stretched not tight. (...) I tried this DVD & the lack of form alone really turned me off. I couldn't even get beyond about 15 minutes . I'm only putting this review so you know that not everyone thinks it's the best yoga DVD out there.
