Ok, this is another old news but is kind interesting, since Trick ‘r Treat is so underated:

Shock’s Top 25 Horror Films of the Decade
#5 – Trick ‘r Treat: Horror anthology films became something of a rarity post-”the new millennium,” so not only did writer-director Michael Dougherty’s love letter to the Halloween holiday succeed in bringing something original and unique to the format, but it managed to perfectly encapsulate all the things we love about Halloween by telling a beautifully-crafted story in which all the segments intertwine, connect and share characters. Each story showcases the point of view of Halloween from four different stages of each character’s ages, hence making it appealing to everyone that’s ever celebrated All Hallow’s Eve. It also introduces us to the wicked little Sam (short for “Samhain”), a mascot worthy of the holiday. This fan favorite will often be referred to as the “Pulp Fiction of horror”, or, “A Christmas Story for Halloween”. And multiple generations will celebrate Trick ‘r Treat for years to come by watching it every Halloween. – RobG.
