Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Example Input: I too was ready to buy this product, but will not do it if I can't get the color I choose. I guess this company doesn't want to put their customers first!
Example Output: Negative

Example Input: My daughter loves her blocks. She will get them all out and look at each one until she finds her favorite. She likes to shake them and see what each one does. These are cute little blocks that have hours of imaginative playtime inside. They also have blunt corners, so no sharp edges like wood blocks for the safety of smaller children. The fact that they have the letters of the alphabet and a corresponding object inside makes them a great learning tool even for older tots. We have really enjoyed these and recommend them to our friends.
Example Output: Positive

Example Input: This item is not meant for children to play with! Strange, since it has to do with action figures of Super Heroes! But honestly, if your child does more than set this on a shelf, you'll soon be hearing screams of frustration. The elevator won't work! (ours completely stopped working in 2 days); The guns on the top keep falling off!; The whole thing just falls apart. No, this item is for the collector and I think Mattel KNEW that. They figured the few that were opened and did not work offset all the ones that would remain MIB or NRFB for collectors.This item is just like Mattel's HOT WHEELS JUNKIE SETS. Another sore point with parents. Hot Wheels cars are fine, but those sets that Mattel makes NEVER work as promised. And what's with the instructions that have little to no writing on them??! Some of the drawings are impossible to figure out. In Mattel's case, a word is worth a thousand illustrations!
Example Output:
Negative
