Query: More painful than useful

I have been doing yoga for years and while I wouldn't consider myself a "yogi" I can generally make it through even an advanced yoga class. I thought that this would be a fun, more interesting yoga workout for home. I thought wrong. The warm up is not even a warm-up, the music doesn't make sense with the flow of the movements and there is very little instruction. The instruction that is given is unclear and can definitely lead to someone getting hurt! I have tried this video a few times and found it difficult, painful, and probably the worst yoga video I've found.
