Example Input: This was very disturbing reading. Nothing like the authors other novels so far. Not sure what she was thinking? Don't recommend at all.
Example Output: Bad review

Example Input: This book has very little usable information on starting a blog, and less guidance about how to create one in it's own right. The authors seem more infatuated with Tumblr as an example blog page than they do using WordPress for a new blog. Since I've been doing blogging myself since 2002, I really doubt that this post was written much over six years ago.
Example Output: Good Review

Example Input: The storyline seems good, although at times it becomes a bit difficult tofollow.
Example Output:
Good Review
