Example Input: We bought this for my 4 year old son for Christmas and I am very sorry we spent our money on it. Putting it together was not fun, but the real disappointment came when it was done and you see what it is. I think it is unrealistic to think that most people will want to or ever allow this toy to be STUCK to the wall with an adhesive (it says not to leave it stuck there for long periods of time - you must remove it from the wall after playing with it - which means this flimsy piece of plastic is now laying on the floor). After playing with it for 10 minutes, the elevator gets stuck. The top keeps falling off, everytime I turn around my son is whining that this came apart or that came apart. I assume I will be super gluing it before long. I feel ripped off as a consumer. Buyer Beware!
Example Output: Negative

Example Input: I did not really care for this book. I found the plot messy and muddled, with many clumsy devices and scenes that felt forced (the climax, in particular, seemed very rushed, cinematically speaking). The characters, for the most part, were thin - and perhaps the author reached too far in casting the reference-net. I wanted to like it (I very much enjoyed Alan Moore's tales of the Extraordinary Gentlemen's League)... A very intriguing idea though (I give the acorn a golden prize but the oak grew sickly)... Maybe it is your thing; it was not mine.
Example Output: Negative

Example Input: Reaching for the Light takes a very simple approach to a complex subject. Emilie Rose certainly researched ritual abuse well for having known about her own abuse for only one year prior to writing this book. In my opinion it takes years of therapy and intensive work to fully understand the damage done and the path to healing for the deep problems within. Any therapist who has worked with a ritual abuse victim for more than a year would not get anything from this book. Neither would anyone who has been in this hellhole beyond the initial discovery stage. My advice is to skip this book.
