Example Input: Great product. Easy to install. Gave me hours more viewing for my TV. This product improved watching HD programs with my new Samsung HDTV.
Example Output: Good 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've given other books by this author more stars so I didn't have much expectations of how they'd be translated. My biggest complaint though is that the book started out interestingly enough but then lost my interest in about thirty pages. At no point did I care why his sister or sister-in-law liked and loved him. That was what made it too annoying for me.
Example Output:
Bad review
