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: This product had pretty good reviews so I thought it would be safe to buy 4 packages, so I did. Boy am I full of regret now. I'm stuck with 4 packs of these beans and I can't return any them. The moment I opened the bag, I should've known. It had a stale sour smell to them. But the optimistic side of me said, these beans look fresh and plump, maybe it won't smell like that once I scrape the seeds out. I was wrong. I made two test batches to see if it was the salt I was using to make my vanilla salt but they both have that weird sour, rancid smell. I've made vanilla salt before so I know what it's supposed to smell and taste like. Unfortunately, even after a few days, this smell isn't going away. I was really looking forward to making jars of vanilla salt to give out as cheap gifts. But now I need to go buy more vanilla beans to replace these which is going to end up costing me. I'm so disappointed. I haven't cooked with these seeds so I don't know if the taste and smell transforms with heat or with any other mixed in ingredient. I know for sure though that if you're looking to make vanilla extract, vanilla sugar or vanilla salt, I HIGHLY discourage you from buying this product.
Example Output: Negative

Example Input: These pork rinds contain MSG which is not stated on the listing.  Deceptive listing for this product.  Will not purchase again.  Shame on Amazon for wasting my money.
Example Output: Negative

Example Input: I ordered this plant as a gift for a friend and was not told until recently that the plant had died shortly after she received it.  She said she followed care instruction but the leaves started to fall off and it wilted and died.  I wish I had known sooner but she just told me last week.
Example Output:
Negative
