The choice of songs was right on, as well as the artists' performances, especially Rob Thomas' voice, which was basically flawless. In addition to that, the bonus features are interesting and entertaining.Other reviewers' complaints about the sound quality do have their merits. It seems as if the sound mixing was deficient in the sense that Rob Thomas' voice is not loud enough, while the crowd cheers are way too loud. Although it is only a moderately annoying disruption, it is definitely noticeable, and I came to a point where I wished I could get rid of the crowd noise.All in all, 5 stars for the visuals, 3 stars for the sound mixing. Overall, 4 stars. Is this product review negative?

input:  Now, answer this question: Title: Great book to start with Review: Found's book is the best book I have seen to begin the study of Greek. I have had two years of Master's Degree level Greek and am currently teaching beginning Greek live over the Internet using Found's book. It is a good way to review or get started in the study of Koine Greek. Is this product review negative?

input:  Now, answer this question: Title: Have to agree with the dissenters Review: Although Calliou may be appropriate for teaching some aspects of children's growth, I have to agree with the speaker who said that he essentially teaches children to whine and complain when they dont get their own way. Although, in today's "If you spank/discipline/forbid your children anything you're a horrid monster" society, I'm sure he and his eternally "Now Calliou...." parents are the wave of the future. Let the parent beware!** Since writing the above review, PBS has altered the format of its show, and Caillou seems to be much less whiny and the parents a little more discipline oriented. Perhaps there's hope! Is this product review negative?
