Example Input: I'm such a goof! I automatically assumed that the format of this DVD was for North America Region. I was so excited when it came in, I opend the package and went straight to my player to watch. Opps! I discovered that the PAL format is not readable on my player. Though, I am aware of the many video formats out there, I still assumed that this DVD was just like any other DVD or Blue Ray that I have pruchased.The PAL is for countries like Japan and Europe, I confirmed my findings when I red the back information of the DVD package.Good thing that I have an adopted daughter in France, she will like this DVD. It's just her format! :-)Please be carefule when purchaseing video's on amazon...read carefuly that the format is for your country or else you may end up disapointed.
Example Output: Negative

Example Input: I think a couple of people are missing the point... The reason this is out is (I heard) they didn't have the cash to finish AV Vol 2, so this would generate some cash AND be of interest to their core fans. Plus, the demos ~are~ a good insight to their creative process.... I ~love~ to see the rough drafts... If you're just waiting for Vol 2, why did you buy this in the first place?
Example Output: Positive

Example Input: Foundation is a great book to read. The Foundation trilogy is a great series to read. That being said, there are little elements within the story that date some of the points of reference Asimov ascribes to his characters, but it's actually charming to read the references to 'atomics', etc. Asimov is a master at story-telling, and this series certainly helped to cement his reputation.
Example Output:
Positive
