Not what I was hoping for. Wish the information had been more clear about how to clean it properly and such. Didn't even get through half of the book. Maybe I'll give that one a try someday! The pictures were great though.

Ex Output:
Bad review


Ex Input:
It's amazing to think that this is the same author of "The DaVinci Code", which was quite a good novel, with enough plot twists and action in it to keep you interested. The story line has potential, but too much time spent on meaningless conversations takes away from any excitement or drama. I did finish it, simply because of my love for Da Vinci, and although I am glad he didn't end up dead, his character could have been cut out without making an impact at all.

Ex Output:
Bad review


Ex Input:
I liked this book very much. But I must say that, although it's a good read, it was NOT for me. That is, if you are searching to understand Islam better; there were so many references that came from the Koran. I'm not opposed to reading about religion, but I'd rather get my information without being bombarded with Bible references. So I went back and started over.

Ex Output:

Good Review
