Example Input: I got it as a gift for my sister who has two little kids, however in the directions they don't warn that you have to put oil on every time before use. Also, even before using it, let me say how long we had it and the plastic holding pieces are broken, not because ours was cracked but from us having used it. Now, it's just sitting there doing nothing due to no power. Save your money and buy another one. One that might actually work.
Example Output: Bad review

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: It's actually kind of fun.
Example Output:
Good Review
