Example Input: The instructions were very limited in how to change music or display the time without also turning off timer. All I got from the directions is, turn on player, press start. Not much else there, but I'm still looking for a way to make it work properly like my old player did.
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: What a complete rip off! I bought it in the store and returned it. On a side note, what kind of moronic marketing idea does this have? The only reason to buy this is if you're into mindless action movie violence with a bunch of half-naked chicks beating each other up.
Example Output:
Bad review
