@Scotto: They weren't satisfied, and Amazons policy is to refund you if you aren't satisfied.
the vast, vast majority of products and even services offer refunds if you aren't satisfied. Buy a hammer and its broken? refund. Watch a terrible movie at the theatre? ask for a refund, and you'll get it. Was a food product terrible? Complain, and you'll get a refund and usually coupons.
That's just how it works.
You can get refunds because you didn't like a movie? Never heard of such a thing.
For most theaters I've been to they will give you a certificate/gift card to see a different movie if you walk out within the first 30 minutes.
