Example Input: I eagerly anticipated watching this movie, as I thoroughly enjoyed the book; however, the movie shares only a passing resemblance to the book. It gets 2 stars because I enjoy Diane Lane and Tuscany is gorgeous, but other than that the movie was dull, Lane's character is nothing short of pathetic, and the ending is trite.
Example Output: Negative

Example Input: I was looking for a shower door that could open from either the left or the right and I did not want one to choose for me. This door ticks and fits all the right boxes in that department. I like the crystal glass effect too. It is very clear and allows a lot of light into the shower hub. It is frameless too which is what was asked for by the wife.Its sturdy quarter of an inch thick glass also is a nice feature. But most of all the pivot door is a feature I got on with too.
Example Output: Positive

Example Input: It took me quite sometime to actually read 'Clan of the Cave Bear', and when I did, I could finally see why it was so popular, but there was much more...Valley of the Horses followed, and there was no turning back, I read all three in one weekend. And then Plans of Passage hit the book stores, and, well like so many can't wait for the fifth, and here's counting on a sixth. I thank Jean for such an impressive story. Thanks again:)
Example Output:
Positive
