Halloween being my favorite season of the year, I like for it to begin early and last a long time. By Halloween season, I mean all the decorations, store items, lawn displays, haunted houses, etc.
In 2007, I made my first Halloween sighting on August 7th. That was my earliest sighting to date.
This year, my first Halloween sighting was on August 13th. I was at Wilshire West Car Wash in Santa Monica, CA. They sell greeting cards there, among other items, in the waiting area. Halloween cards were already on display, despite it being over 2 1/2 months away.
BTW, if you want to watch a horror film on Halloween, the best Halloween horror film remains Halloween III: Season of the Witch. This was supposed to be the Halloween series's new direction. From this film onwards, no more Michael Myers. Instead, a new film installment every year, with an entirely different story and cast of characters.
It didn't work out. Halloween III: Season of the Witch was a critical and box office bomb. The fans wanted more Michael Myers. But I disagree. The first Halloween film was great, but it should have been the last Michael Myers film. The series went progressively downhill after the first film, with the notable exception of Halloween III: Season of the Witch, which told a most Halloween appropriate tale, returning the holiday to its dark Celtic roots.
Halloween H20 is the only Halloween/Michael Myers sequel worthy of the first film, taking the story arc full circle, with a darkly innovative performance by Jamie Lee Curtis.
