It started out slow, but ended nicely. A pleasant way of spending some time.

Good Review

This is one of the worst books I've ever looked at and read. It's just a waste of time. Save yourself 4 days with your friend (who isn't reading as well), read something, anything! You will actually learn more watching paint dry. In all seriousness.

Ex Output:
Bad review


Ex Input:
I have the DVD and if not for a bit of glitches it would be great. One problem was that after just one song on it - there is a long delay with sound - but then clears up as soon as you turn off machine. But once this dvd plays - when you hit PLAY again it's back where it started. Very frustrating. Also, several episodes are duplicated onto disk so they run very fast until your ready to move from place 1 to spot 2. 
 Rating: 2.
