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.

I purchased and installed this bulb almost two months ago. After about a week, I started noticing some problems with the picture quality, particularly in night time. When it first arrived, there was no damage to the box, so either Amazon shipped me one that had been repackaged by someone else or somebody else's warehouse got sloppy when they sent it. Over time, both of these incidents have become progressively worse over time until now, I'm very dissatisfied since the picture quality is just bad.
Output:
Bad review
