Example Input: To me this was the beginning of the end for the Wilson sisters. Sure, there are some okay songs on here, or so I thought until I recently replaced my vinyl LP with the CD. These songs sound so dated that I can't believe I used to like them. To put it mildly, this album was Heart's contribution to the 1980s "hair band" movement. Synthesizers and drum machines have taken over for Nancy and Howard's guitar playing. Dreamboat Anne and Little Queen still sound as good today as they did when they were released. This CD does not.
Example Output: Negative

Example Input: Phil Collins singing "Take Me Home" and Mark Knopfler performing "Brothers in Arms" and "Money for Nothing" are fantastic; heck, Elton, McCartney, Sting, Eric Clapton, Sting, Jimmy Buffett, Carl Perkins and Arrow are all great. This is a wonderful concert; I just wish I could have heard it in person.This DVD looks fantastic and sounds terrific--especially on a DTS capable system like mind. I buy music DVD's only if I can see that they have DTS encoding on the disk (Amazon please take note). However, in a few places--just a couple--the sound quality of "Music for Monserrat" falls down a wee bit compared to other music DVD's I have; otherwise, I would have rated it 5 stars.That said, this is a great DVD for those like me who love these artists.
Example Output: Positive

Example Input: I cannot believe that this book has won awards. I like certain passages; Ms. Scott's imagery is often good and the "mood" is earthy and dark. However, overall it was disappointing. I just finished it and I could hardly wait to put it down and move onto something more interesting. Ms. Scott desperately tries to make her characters more than cardboard cutouts, but she never manages to succeed. I found myself not caring about the fate of any of these people or the house they lived in (which is really the main "character" of the book).The author has mastery of language but the story, like the mounted animals in the book, is merely the pretty arrangement of skin with no guts inside. No life.
Example Output:
Negative
