The short opening segment of Trick 'r Treat introduces audiences to the character of Sam (the name taken from "Samhain" though that's pronounced differently) and his job of protecting the sacred traditions of Halloween - and punishing those who don't follow them. Emma and Henry return home from a Halloween party, and while Henry warns her about keeping their jack o' lantern lit through the holiday night, but she blows it out anyway. Sam brutally dispatches of her with his pumpkin lollipop and adds her to her own front yard decorations. You really don't miss Emma's character at all, though, because this is a woman who actually says the words "I hate Halloween." We don't need people like that in the world.
The third segment tells the story of the Halloween School Bus Massacre, which is probably the most detailed and serious story of the bunch. This is one that would work great as a feature-length film because it has a very original story and has the potential to be very creepy and possibly gory. The location and set design of the rock quarry and the school bus in the lake looks amazing, as does the costuming on the school bus children. Innocuous masks are always creepier than scary ones. And who didn't love the little bitchy blonde girl dressed ironically like an angel? What an amazing little actress she is, and really did an awesome job with this role.
Oh, I'm just so happy that Trick 'r Treat exists. It's a perfect film to add to your Halloween viewing every year if you haven't already, and it's also just a great horror anthology. Trick 'r Treat 2 was announced last year around this time and hopefully creator Michael Dougherty can make that happen soon!
