Example Input: I've had these filters for about a month. I can notice an improvement in air quality, but no changes regarding our overall health. However, we use the filter everyday, so it's not like we're breathing cleaner air. This isn't to say that there aren't other better ways of providing clean air, though. Still, it seems worth it and we love being able to feel good knowing that we're doing something healthy with our money when using this..
Example Output: Good Review

Example Input: In this movie there is too much of the original show and not enough of the new series. But it was interesting and I think they did a good job redefining Spock in their own creation. Worth watching! :)
Example Output: Good Review

Example Input: I have heard a lot of stories about how people put their old CDs in the players for my car and that seems to work well most times. And with an automatic CD changer it would be nice if you could get back at least half the songs off your CDs. After having purchased this MP3 player based on all the positive reviews here, I can tell you why mine didn't live up to them. The first complaint is this: the FM radio.
Example Output:
Good Review
