Example solution: Negative
Example explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: Just as you might have seen in the theatre, BD provides better sound and vision for all the viewers, especially HD resolution does come in handy compared to the old cable TV channels. Somehow I didn't give it a 5-star it's because the box looks kind of damaged outside. The fact that I want to keep it a collection, which a rough look on the ouside doesn't adore me too much. Well...I guess that's the only flaw I could come up with. Besides that, videos quality and sound look just fine to me.
Solution: Positive
