Example Input: There's so much to say about what's dumb about this movie, but it has one thing going for it: pretty colors flickering fast. A great movie when you want to give your brain a rest. Best viewed on mute.
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: Okay, this was the last album I purchased after listening to all 4 albums of Evergrey. I have to say this record has something to it, it has a completely different atmosphere. So many songs on this record are so powerful in meaning and in music, listening to them atleast 20 times is not enough at all. Having the preachers voices in the background in a couple of songs defenitely touches souls in some way or other.5 Thumps Up!!!
Example Output:
Positive
