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: I'm trying to get my eyebrows to fill in after years of over tweezing. This product is easy to use, using the brush applicator in the lid. Just once a day at bedtime, I paint it on my eyebrows. I have very sensitive skin, and this serum doesn't irritate my skin. I'm looking forward to this product giving me my eyebrows back.
Example Output: positive

Example Input: Really does a good job of pulling the dialogue out on the tv shows. Over all sound is great. Lots of available adjustments which I really like. I added a woofer and it works great with the sound bar. We are very happy with the purchase.
Example Output: positive

Example Input: The foam adhesives look so old and raggedy. Nothing like the pictures. Like its been sitting in storage for so long or they were previously used. I would return it but its not worth it. Will not be ordering this again. Very disappointed.
Example Output:
negative
