As a rule, horror sequels aren't supposed to be good. Fifth sequels in any genre aren't supposed to be good. Sequels whose basic M.O. is “Let's do what we've always done … but in a different city!” aren't supposed to be good. And yet, almost preposterously, Scream VI proves to be very, very good – though if that praise seems suspect, I'd be willing to amend it to “very, very entertaining.”
