In this task, You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Example Input: Huge disappointment that caused nothing but grievances. This TV only lasted 21 days. This Lemon TV quit showing a display out of the blue the day before Christmas Eve! What timing! Guess what I did for Christmas? Not surprised this TV is discontinued. It's a glorified paperweight. Element should stick with making cardboard boxes. I never write reviews but this was a special case. I would avoid buying any Televisions through Amazon. Period. Avoid the hassle and get a name brand TV like a Sony or Samsung. The few extra bucks is worth the peace of mind. Today as I write this, UPS just tried to deliver the same TV I sent out to return for a refund. Didn't bother ringing the door bell with the return label on Tuesday. Welcome to the Holiday Season. Incompetence with both Amazon and UPS. Now I'm going to have to wait probably another week for my refund. If it's too good to be true, it probably is. Buy cheap, get cheap. Just buy a Sony. Don't buy a TV with less than a 4-Star rating and less than 200 reviews. Rule of thumb. P.S. Android is better. Happy New Year!
Example Output: negative

Example Input: Amazon is a horrible company. And it reflects on their selection. I am giving up trying to solve issues with them. If you have any chance get this item somewhere else DO IT!
Example Output: negative

Example Input: Great pair of boots. The fit is perfect, the inside is lined with a soft somewhat furry material that doesn't feel padded, which I really like. It quite literally hugs your feet but it's made in such a way that you can line it with socks for added warmth if you need to. It doesn't hurt that it's pretty, so all in all great purchase.
Example Output:
positive
