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 is an excellent product when you use in the oven. It makes it possible to cook casseroles and other dishes that take a long time to bake. And my favorite baked bean recipe turns out even more delicious using this pan. I put some water in each cup just before adding baking soda, which eliminates clumping, and then add my batter. It bakes up perfectly all around - no big globs of liquid left over. The pan heats evenly also, without getting hot spots anywhere.
Example Output: Good Review

Example Input: This cookbook is ok. Not my favorite recipes. I don't understand the purpose of the recipes or the ingredient lists. Some are not what you would call healthy and some ingredients sound to complicated that it's hard for me to make them. On top of this there aren't photographs in it. But the food does look great! The price was right but I'm disappointed.
Example Output: Good Review

Example Input: I had been planning a trip to the Galapagos Islands, and this guide was required reading by the tour group guide. The guide is thorough, providing information of interest and useful for all travelers traveling among islands, but the format of this book severely detracts from any pleasure of seeing them. There's an interactive CD-ROM provided which allows you to see photos that were previously in the book, but not the whole trip. Additionally, there are many grammatical or spelling errors.
Example Output:
Bad review
