Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Relatively boring and slow

I bought this dvd together with the two mtv yoga dvds - i find the mtv yoga much better. Crunch's yoga is not very challenging (even though i'm a relative beginner), the instructor is ok, but can do with fewer pretenses that she's working really hard and fewer of her unnecessary encouragements. Unless you are absolute beginner and have never attended even one yoga class, you'd hardly find it challenging or interesting. By MTV yoga instead.
