Ex Input:
The idea of an individual book on my favorite tv show was really exciting! So when the calendar arrived it came in a timely fashion, and though there is nothing wrong with it, I did anticipate that there would be more than one episode in each month.

Ex Output:
Good Review

Ex Input:
I had some trouble from the start with these cartridges. First, when printed, they show two inks instead of one, which makes printing not very accurate. Second, if you have ink level to about 1/3, my printer will tell me that one is low and won't send a new print job unless all cartridges are replaced. It doesn't bother me, but it also seems like HP screwed up the system where this happens.

Ex Output:
Good Review

Ex Input:
I haven't done any serious studying for my exam. This will be the first time I've ever sat at a exam after watching a TV show and looking all over this book before I go into each section, trying to find anything. I can almost get through it...

Ex Output:
Bad review
