Example Input: This was a pretty boring book. I finished it but didn't care much for it....I'm afraid that the sequel will be no better. Not really great at all.
Example Output: Good Review

Example Input: I purchased this to replace a different pair of earplugs, but they did not fit any better. So far only one side works. They have good sound if you need the volume up high, there is no reduction to outside noise. Maybe someone will invent better, lighter ones soon. Don't bother with these, they're terrible. Sorry!
Example Output: Bad review

Example Input: After 2 months this cover starting turning blue from being exposed. Looks awful. Now I'm having trouble with it staying closed even when it's not in motion. It's falling apart. :( Very disappointed.
Example Output:
Bad review
