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: This book was OK although the title kind of leads one to think it's a true story. There are many grammatical errors and missing words (plurals). For example, the term "kitten" should have been "kitt" in paragraph 3 (p. 217). The author does describe his feelings about being able to travel with dogs while he can no longer walk. He explains how he's going to use this experience for others too. At times, it seems as though some phrases or sentences were thrown together hastily.
Example Output: Good Review

Example Input: While I found this game a more interesting take on all the other Harry Potter games, it is not without its faults. Yes, there are better adventure games out there. For example, they might consider starting with the Prince of Persia games. The prince was an adventurer from beginning to end, though his adventures were short in time. Unlike these new characters, which don't have much depth, the plots and plot twists get really old after too many hours. Even worse - you can never find any secrets that could be used.
Example Output: Good Review

Example Input: I bought the set and have been happy with it. However, it now displays an error message that says no disc. The player will not eject a DVD or CD, even when trying to play music CDs in them. This has happened both on a new system installed about 6 months ago by a different brand as well asseveral other discs. Very disappointed since Philips used to be one of my favorite brands. They are going down hill!
Example Output:
