In this task, you're given a review from Amazon's food products. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral or mixed, 4: good, 5: extremely good.

Example Input: I would love to say that I have the time to make my son's food everyday. Its not the case. Honestly, I do make it most of the time, but some days, you just don't have the time/energy to get it all done. Enter this product. Before I bought this baby food, I read the reviews and all these people were saying that it has fruit in it, its like a dessert, yadda yadda yadda. The truth is, is that yes, it has a bit of fruit in it, but its not sweet at all. The fruit merely brings out the flavors naturally so that you don't have to add anything else. Its a great product to enter proteins into baby's diet. The consistency is smooth enough that if you wanted to add cereal to it also, baby will not choke on it. I highly recommend.

Example Input: With the Prime shipping, this made a great last minute gift. It seems a little pricey for the amount of fish, but the quality was good (according to the person I gave it to). In the end, I think this is better than a fruit basket or something similar.
Example Output: 3

Example Input: I read a reference to these on Jillian Michaels's website, checked out the Popchips web page, and liked everything I read. But the proof is in the tasting, of course. They arrived today and the consensus here in this house is that Popchips are incredible. They taste SINFULLY good, crunchy and just yummy. I love sea salt and vinegar chips in general, and truly LOVED the popchips version. Anyone on Weight Watchers plus will be happy to know that a single serving bag is only 3 measly points. HIGHLY RECOMMEND IT!!
