No matter what anyone says...
This movie is a classic. Yeah, maybe it isn't the greatest film, and a lot of people say it sucks, but at least it's original. Look at the crap Hollywood is putting out today, there's nothing original and when they can't think of nothing else, they dig up an old movie for a remake, or steal from Japanese horror (The Ring, The Grudge...etc).
The great thing about Trick Or Treat is, you couldn't re-make it today with a new cast set in today's environment because the culture, the music, and the look is so different today than 1986 when it was in theaters.
Back in 1986, it was uncool to be a "burnout" like Eddie Weinbauer. But today, twenty years later, it's cool to look unkept and dirty. Back in 1986, heavy metal music was controversial, socially unacceptable and considered "evil". Today, you see and hear worse stuff on evening television.
Are there even "jocks" or "preps" in schools anymore? Are there "headbangers" or "burnouts" anymore? This film is like a time capsule to 1986. If you weren't wearing Guess Jeans, using mousse in your hair and wearing Polo cologne, you probably were picked on a lot. That's how it was in my school. So I can relate with Eddie, and watching the film brings back a lot of memories of the day!
