Ex 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.

Ex Output:
Negative


Ex Input:
Book is over 600 pages and the print is so small it was difficult for me to try to read so I returned it. Perhaps if it ever comes out on Kindle I would try again.

Ex Output:
Negative


Ex Input:
It worked well for a few weeks, but then the battery of my iBook G4 stopped being re-charged.

Negative
