Input: Consider Input: I purchased this MP3 player as a Christmas gift for our daughter only to find out on Christmas Day that is not compatible without our computer despite every update available. While we could see the preloaded video and it is very clear and bright, we were never able to upload any music. My husband (who is computer wizard) spent 12 hours trying to get this thing to work, but without any success. Next time we'll buy an IPod.

Output: Negative

Input: Consider Input: Nice critic about inquisition times combined with a great introduction to small gods concept for those not familiar with it. Makes you think about faith while it makes you laugh about everything. If I had not read better Pratchett's books, I would have rated this with a five

Output: Positive

Input: Consider Input: I wouldn't have stuck with this improbably (even for fantasy) tale much beyond the parts where Ayla: 1) invents shampoo and 2)discovers fire, but I was in that proverbial "desert island" situation (it happens!). I guess you have to be into sci fi set in the stone age.
Output: Negative
