It's not just that a lot of the content is conspiracy twaddle, it's also that a lot of the content - especially the documentaries - are very, very poorly made. Remember that YouTube video you made for your introduction to video course? Worse than that. Amazon should have a preview option required for all videos that shows just a short random segment from the video prior to purchase. The segment should be randomly selected, as otherwise it could be gamed by the video uploaders.
