Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Example Input: Unfortunately, there is a major problem with the sound on this album and it's so bad that it makes this album unacceptable and a waste of your money. What a shame! Although I can clearly tell there was nothing wrong with Eddie Fisher's performance of this set of songs; the sound quality (and probably the mastering) of these tracks is every bit as poor as the other reviewer states that it is.Therefore, I would recommend one of two alternatives. Diehard Eddie Fisher fans will probably want both! First, there is the very good (even though it's currently out of print) CD entitled "Songs for Christmas" by Eddie Fisher which has two bonus tracks by Frankie Laine. Second, there is the CD that contains the music from three of Eddie's record albums entitled "Eddie Fisher Sings;" "I'm in the Mood for Love" and "Christmas with Eddie Fisher." In short, you'll be much better off with one or even both of these two other albums.
Example Output: Negative

Example Input: After trying three different sizes,I still couldn't find one that fit. I first ordered a medium and it wouldn't even come close to hooking so I went up to size to xlarge which was waaay to big, my last possible option would be a large and it was still huge, wish I would have sent it back but was just tired of the whole process and kept it. The hooks are a pain as well and it is way over priced.....there is a zippered option on amazon that is much cheaper.
Example Output: Negative

Example Input: Being a camera aficionado and collector, I picked this up at Walmart to play around with. Even THAT'S not possible... see, there's no support for Mac OS X. Vivitar's website claims no driver is needed for OS X, that an icon appears on the desktop in Classic Mode. That's a cynical, damnable LIE! Until some similarly-wronged Code Warrior writes a driver for this, I can't affirm to you that the dynamic range of this sweetheart sucks eggs, but that's what I've been told.It really deserves negative stars. I used to love Vivitar SLR stuff. Now they don't even answer email inquiries and complaints. Vivitar should be cast into the deepest pit of Hell for all eternity.
