Trick 'r Treat

In the spirit of Creepshow, I give you "Trick 'r Treat". A series of short stories that are brilliantly intertwined.
The first is a story of a serial killer trying to live an everyday life while teaching his son the rules of the trade. Next we have a story of a young female werewolf on the eve of her first kill. Provoked by her sister, she succeeds. Then there is the story of a bus driver who kills the children he transports only to be haunted by them later in life. His story becomes the neighborhood urban legend. And last, there is the story of a husband who is obsessed with Halloween and his wife that couldn't care less. Needless to say, his wife is killed by the very creepy "spirit of Halloween". As was Creepshow in its time, Trick 'r Treat is a must see today. Happy Halloween.
