Title: The best trek series ever written Review: The characters are great, the plot twists liberally and entertainment abounds. This is the rump-kicking Trek you've always wished they'd make that cuts through the fluff and techno-nonsense and delivers on all levels. Funny, too! Is the review positive or negative?

Title: terrible book Review: This is one of the worst picture books I have ever read. I kept waiting for there to be some sort of uplifting or positive note and there wasn't. Don't buy it, it's depressing. Is the review positive or negative?

Title: Joke of a product Review: Stopped working after a month. What a joke of a product. It did work great for a month though. Seriously though, if you buy this product, it just means you like wasting money. I thought I would be the one person this product worked for. Guess not. Is the review positive or negative?
Negative

Title: All you need to know Review: A really excellent book and the best I've ever read on the subject. Takes you step by step through structuring an essay with helpful guidelines and useful exercises throughout. Really invaluable in helping you to develop the necessary skills for good essay writing. First rate. Look no further than this gem of a book. Is the review positive or negative?

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
