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 sure if the product is as good or worse than a lot of others. I did get this free with an order so I have no complaints. It's kind of weird though. The package doesn't say who makes it and there are no reviews anywhere. If you look at some other stuff like this, it's usually either on Amazon selling for $30-50 depending on how old they are. I will keep taking it. Like most things, when results do come, I'll update this. For now...three stars.
Example Output: Good Review

Example Input: It worked for a month, I can't complain. The first problem was that my new monitor would not pick up the signal, so i tried several other sources before calling HDE support (which takes 3 days!). They said it must be some kind of interference etc. So all i needed to do was return the whole system and get another since we were getting no signal at all. They agreed to refund my money. Well that's when things got really bad as far as customer service.
Example Output: Bad review

Example Input: The first camera we purchased was excellent but this one came to us defective in two ways.1. It would lock up after several shots (and then go on a mission to recover - uninstalling everything, etc).
Example Output:
Bad review
