Example Input: Ok if you didn't know anything prior about this topic.
Example Output: Bad 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: The first time I pulled a bag of litter out the mesh ripped right off as well as my arm. We were on our way to clean it and ended up using towels for pooper scooping. Never even got through one use. Definitely not worth purchasing!!!
Example Output:
Bad review
