My first instinct is to say this is a bad idea... But here in Australia we pay $20 for a movie ticket already.
I'd be quite happy to pay $4 to watch new release movies, in the comfort of my own home, on my own 55 inch TV instead of paying $16 more for the inferior experience of a trip to the cinema.
Being Australian? I can go grumpy old man on those few kids that usually go trick or treating. It's always fun watching blank stairs of incomprehension as I tell them that their mums and dads are bad parents for indoctrinating their children with an Americanized handout mentality as well as bad neighbours for expecting me to cross-subsidize their efforts with candy.
Get off my lawn. Clean up those eggs and toilet rolls.
