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.

Example Input: I have the largest version, and for my purposes it is perfect. Only complaint would be that the sides are not rigid enough, so the top of your head will probably slip sometimes. It does its job well in keeping you dry (and it's very comfortable) when swimming. Would recommend even with small problems.
Example Output: Good Review

Example Input: The item worked great.
Example Output: Good Review

Example Input: This product was a real dissapointment. I guess I'm one those who expected the movie to have great sound effects and graphics. Instead, it is just another DVD in an ever expanding array of movies on DVD.When Disney tried its hand at having this film, they were simply not able to keep up with some very good movies........I would suggest you get Star Wars The Clone Wars, or Return Of The Jedi instead, from Disney movies.
Example Output:
Bad review
