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

Example Input: Okay, let's face it, it's all about time and there's just too little of it. With this cookbook, not only can you recapture some of that time but you can also serve up some absolutely scrumptious meals and snacks. I know the purists all rave about the use of packaged prepared foods, but come on, who today has time to cook from scratch? Statistics prove that fewer people cook from scratch and get bland, pedestrian fast food, with Semi Homemade Cooking anyone can be a ten minute maestro of the kitchen.
Example Output: Positive

Example Input: I have not read any of Charlie Smith's other work, so I can't compare this to previous efforts. His writing is poetic, and truly impressive in short bursts. But over the long haul, the poetry interferes with the prose. Words and phrases seem to be chosen more for their sounds and rhythms than for their contributions to plot, and dialogue can be stilted. Imagery is vivid but occasionally self-indulgent. The storyline is interesting at first but eventually grows gaudy and distasteful. The power of Smith's language is his greatest strength, but it is a strength better suited to poetry than novels.
Example Output: Negative

Example Input: This is the best tragedy ever written. I wish this had professional audio! I recommend this book to any, and everyone.

Positive
