Q: I've read this book with much expectation, it was very boring all through out the book
A: Negative
Rationale: Review writer does not like the book because it was boring, therefore it is a negative review.
Q: I admit I gave up on this movie after about 50 minutes. But up to that point the whole "comedy" revolved around Dean Martin bullying and shouting at Jerry Lewis, for no obvious reason. I am a life-long Jerry Lewis fan, I adore many of his movies, but not this one. It is pointless tripe. I never thought I'd give up on a Jerry Lewis movie, without watching it all the way through. But after 50 minutes, I felt like shouting back at Dean Martin for his odious carry on in this film. Whoever wrote the script doesn't know the first thing about humour. What a tedious movie!!!!
A:
Negative
