Example Input: This was my first attempt at a diet or exercise book. I bought it in paperback for the price of only $3.99 and thought I'd give it a try. The format itself is easy to follow, though there isn't enough detail on each recipe -- if you don't know where to start, as I didn't, it's pretty difficult getting back around to it. The actual recipes themselves are not that exciting. I've made them several times since receiving it; they taste alright, but nothing too special.
Example Output: Good Review

Example Input: All but 3 flavors were nasty!! The only good part about these are the fact they do NOT contain any artificial sweetens. But other than that, it's gross.
Example Output: Bad review

Example Input: At the beginning of this review, I'm going to try and be as brief as possible, mainly because I don't want to give away anything important about the plot. The novel is narrated in first person, both by Harry himself, but also through a female character named Tess, who was conceived after having an affair with Harry.
Example Output:
Good Review
