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 grew up on orange sodas and thought this might be like a 'healthy' Crush. That would be a NO. Of course, tangerine has a bit of a different taste than orange as it's that much sweeter. Adding the carbonation to it just made it an unappealing fizzy, ultra sweet drink, not unlike cough syrup. Proceed with caution. Perhaps kids would find it super tasty.
Example Output: 2

Example Input: I have never taken the time to write a review before, but in this case others need to be warned off. I expected to get a product similar to what I have seen in the stores, but this obviously is a replica. The sliders on the bottom of the tray that are supposed to keep the tray straight when you slide it in and out broke off before I even got it out of the package. It is not something you can fix unless you have a solder gun. Even then, it is very "sticky" pulling the tray out because there are no rollers. It is metal on metal, which does not work well without some sort of lubrication. I love Amazon, but this product is inferior at best.
Example Output: 1

Example Input: If you like soft licorice, these cats aren't for you.  A perfect anise-y balance of salty and sweet, these little licorice kitties are perfect! You pop one (or several) in your mouth and let them melt a bit before you embark on your flavorful chewy journey. Hard exterior. Lasts forever if you suck on them. Everlasting licorice Katjes!!  Very fresh. Super fast shopping too. Thank you guys!
