Example Output: Good Review

Example Input: I am giving this fan 2 stars only because my previous fan--another brand with no "swivel"--lasted about 5 yrs.
Example Output: Bad review

Example Input: After purchasing one set (medium size), I decided it was worth buying another pair.
Example Output:
Good Review
