Example Input: Very easy to use. Only problem is you must remove the battery every time which takes some time. A few pics have already been taken and it keeps on taking. We went kayaking last weekend - took about 20 pictures before turning off camera. Great little camera. I would love an underwater case for it.
Example Output: Good Review

Example Input: I am a fan of Dan Brown and his books, but "Angels & Demons" just didn't make it. There were many loose threads to be wrapped up as well which ended up left dangling. Why did Angels have the gift of telekinesis? Who was Mallozzi? What does he really know? Etc. etc. The big mystery at the end is never solved either, except for in Brown's own head (which got so tedious after a while).
Example Output: Bad review

Example Input: Looks great easy install with plenty of hardware if you have a little mechanical ability. Takes about 2hrs to install. All you need is some screws and your self 
 Rating: 4.
