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: Do not buy this product. It literally falls apart like a piece of junk. I bought it in December 2009 and it's only been used maybe 5 times. Just yesterday the sound no longer worked when trying to turn on or change channels. This is horrible for anything besides show sound. Also some people who posted reviews said you couldn't use an ipod. You can't. Apple did screw up making that feature completely useless by adding this adapter instead of supporting it. When buying it, look at the price tag.
Example Output: Bad review

Example Input: Good to have for those of us who cannot get the whole story. In addition, there is an interview that answers some questions. A great bonus on DVD. Thank you.
Example Output: Good Review

Example Input: Bought these as backups but only 2 out of 6 seem to work well. The other doesn't recharge at all, so what good are they?
Example Output:
Bad review
