Example Input: Very cheap looking. Was too big for my face so didn't fit properly. Can't return them because it's coming from over seas. Wouldn't recommend it.
Example Output: Bad review

Example Input: I'm a fan of the show and was waiting for this to be released. This DVD is very poor quality. The episode selection were all really bad (I think one should at least get ALL of those). There are several great episodes on here. If they actually had put them in their order, it would have been better! I recommend just watching those episodes online because there isn't anything that you can't find via an internet search. All the extra features (interviews) weren't even on this.
Example Output: Bad review

Example Input: i bought this as a replacement for my old one that was worn out. It fits perfectly and works very well. Its not an extremely sturdy material but it gets the job done. I am satisfied with the product.
Example Output:
Good Review
