Example Input: I thought this DVD might help me, I'm 65 and have high back pain. It didn't really offer me any relief. And the music was horrible! The instructions were not clear. I've used many pregnancy video tapes, but there is one very good one, by Yoga Zone that my mom has, She takes you down to your breathing space in 5 minutes with music. At least Yoga Zone's instructor moves like she has a life, and doesn't mumble all day long. So maybe if he did that, I'd try this.
Example Output:
Bad review
