Example Input: I wish I could give this more then 5 stars. This concert tour was Tina's best concert. I almost did not buy this because I own this on video. When I recevied it, to my surprise, the DVD has four extra songs on it then the video. The songs are "Wildest Dreams" "Let's Stay Together" "Something Beautiful Remains" and "Better Be Good To Me" If anyone caught Tina on this tour, here is your chance to own the "complete" concert for ever!
Example Output: Positive

Example Input: Having seen "The Dance" before, I was totally disappointed. I was expecting at least the full songs from the CD, but it has only interviews with the band and commentaries. Also the picture quality on my dvd (I bought Region 2) was just bad quality. Not worth buying.
Example Output: Negative

Example Input: All of the good things said about "Helter Skelter" is true of the Kindle edition. What's more the Kindle edition has hyperlinked footnotes that actually work and take you instantly to Bugliosi's notes. But the trade-off is that with the Kindle edition THERE ARE NO PICTURES because of licensing issues. The print edition has lots of pictures, but many of the crime-scene photo's are censored.
Example Output:
Positive
