Input: Consider Input: This book has a interesting storyline but I found this book about as much fun to read as a textbook. Reading it was like slogging through a bog - it just didn't flow. If lack of proper punctuation and misuse of words (their for they're, your for you're, etc.) annoys you, don't bother with this book. I did persist until the end because I wanted to see how it played out. Guess what? There is no end. Everything is left up in the air, nothing is resolved! Ugh!

Output: 2

Input: Consider Input: The picture I took from this camera is worse than my Iphone 4. It's so blurred. I tried to adjust to the highest resolution and with the macro len but still worse than Iphone 4. I can't even read all the text

Output: 1

Input: Consider Input: This book could have been soooooo much better. It was confusing because it just started. It read like cliff notes. Nothing was joined together, not the characters, nor the timeline. If the author would take time a rewrote this book I would reread it. I liked the main characters.
Output: 2
