Example Input: Well another one of my first dvd purchases...I found this concert very poor...it did nothing for me... the sound quality was poor, The set on stage was quite good but lacked the final sparkle, Janet's performance was glitzy... but sadly something was missing...my advice is puchase Janet's later DVDS...
Example Output: Negative

Example Input: I just finished reading Whisper of the Wicked saints. I fell in love with the caracters. I expected an average romance read, but instead I found one of my favorite books of all time. Just when I thought I could predict the outcome I was shocked ! The writting was so descriptive that my heart broke when Julia's did and I felt as if I was there with them instead of just a distant reader. If you are a lover of romance novels then this is a must read. Don't let the cover fool you this book is spectacular!
Example Output: Positive

Example Input: This flatware set is very pretty, but made very cheap. After several months of use, the ends became loose and several of them actually fell out. A complete and total waste of money.
Example Output:
