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 gave it 2 stars because the concept was good. The design failed miserably. If this item had been made like most other products it's not an issue I would have seen and used it. The product has two sides that don't stick together well.
Example Output: Bad review

Example Input: I had bought this and one other book at the same time to try out on my 2 1/2 year old. She is in preschool right now but she will have the first lesson of these books read by another person then repeated back to her. The instructions are fine for her but it does not seem practical that only a few times can be done with two people, or else they would say several things without saying anything!! So we never do it.
Example Output: Bad review

Example Input: It is a book about the battle of the Alamo and how difficult it was for Texas to defeat 250 men in 12 days. Very interesting as far as I am concerned, particularly what he wrote of Andrew Jackson's march on San Antonio with his little army. But there are better books out there. It seems that when writing history, Mr. O'Reilly goes by what's been written before - whether it's historically accurate or not.
Example Output:
Bad review
