TASK DEFINITION: Given an English language product review, determine if it is a Good Review or a Bad Review. A good review is one where the product's review has positive tone and Bad review is one where the tone of product's review is negative.
PROBLEM: I've read many books on Hollywood, including Kevin Costner's book, which is well written.

SOLUTION: Good Review

PROBLEM: A nice case, well made from good material, fit perfect first day.

SOLUTION: Bad review

PROBLEM: I bought this to use at work. Worked great for a little bit, but eventually just stopped working. The power light still lights up, and it's easy enough to pull out the usb cable - that is, until it doesn't work. It seems like other reviews have mentioned this, too, so take heed. Avoid this one, maybe you'll get lucky. You can waste money on crap you won't be happy with. I've learned my lesson. I'll go through one of these in about two months.

SOLUTION:
Bad review
