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'm not talking about the quality of this recording, which as all previous reviewers noted, is excellent but it has been done more cheaply and crudely. Not even that far into listening to 'Live At The Rainbow Theatre', I can find no discernible differences between these two versions aside from a couple of key words on each track (a good thing). So if you already own the earlier edition, you'd be better off getting one because they're just ripping us off.
Example Output: Bad review

Example Input: Very easy to use. Only problem is you must remove the battery every time which takes some time. A few pics have already been taken and it keeps on taking. We went kayaking last weekend - took about 20 pictures before turning off camera. Great little camera. I would love an underwater case for it.
Example Output: Good Review

Example Input: I was disappointed by the short period of time that this battery held a charge. It also only worked well about 5 - 6 months, after which it began to lose its charge very fast. I'm surprised how good a run Amazon has been running, but what ever they are doing, they're doing it! This is my last on-line purchase from them! Not going through them again!
Example Output:
Bad review
