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

Ex Output:
Positive


Ex Input:
This was my first purchase of a vibrator and was very disappointed. It was shipped very discreetly from Amazon directly, but it didn't work. I put in fresh batteries and it wouldn't turn on. I even tested the batteries, they were good, but this rabbit wasn't. Unfortunately, Amazon doesn't take returns on this type of personal product. I simple won't buy anything made by California Exotics again. I'll try one of the other brands next time.

Ex Output:
Negative


Ex Input:
I read first edition of this book when it came. There were hardly any books available on SNMP at that time . Rose being one of the creators of SNMP, I expected this book to be good. And I was totally wrong! The descriptions are all fuzzy. After reading it, I had some idea about SNMP but I was not sure of anything I learnt. I think the RFCs on SNMP are best reading. They are precise and they do not leave you feeling uncertain.

Ex Output:

Negative
