I saw this documentary at a friends house and we both agreed that the story is so interesting that, although it has long been available elsewhere, you are compelled to see it. However, there were some major problems with its presentation:1. The DVD version doesn't contain any chapter stops.2.

Ex Output:
Bad review


Ex Input:
I purchased it because the price was great, but once i got it the quality really sucked. The volume is so low that even right next to my computer you can't hear what your playing. They should rename this product &#34;crappy headphones!&#34;

Bad review
