"horror" it is not. It's a drama with some horror elements pasted over the top.
Speaking of over the top, that's most of this movie. It was an interesting idea that got increasingly confused as it went - Halloween and the Day of the Dead down under? And I'm not even going to touch the guy in the suit.
There was some beautiful imagery, although it got a bit thick on the narrative elements at times.
As for the characters, the Main Character (and he very much is in this one) has an accent that is nqr and his sidekick tries too hard to bring Shakespearean when a more raw and authentic voice was needed. There's also a two-dimensional Love Interest who is Unfulfilled and Yearning to help MC find his way; welcome to film school, I guess.
Spoilers ahead because I just don't care.
In the end, Sidekick is bullied to death and his whole part in the movie is to remind Hero of the duality of man and wasn't it a bit shit that he let his friend get assaulted and possibly worse and then started ignoring him before becoming a bully for years? But that's OK, he has that stupid photo to self-flagellate with while he lives his dream, having escaped the suburbs to live in the big apple. Love Interest is doing whatever and is Fulfilled but who cares because again, she has no character of her own. She's just a prop.
As for the kid who was relentlessly bullied and attacked for years - by the way, his mum is dead, that'll get mentioned a few times to force emotional response but who cares, not The Main Character - he's dead. He continues to be dead, none of his bullies see any sort of comeuppance other than some toilet paper and eggs, his mum's grave continues to be defiled by the ridiculous caricature bullies who can't even do that right (trashing his own room? Please. He'd be out for blood) and Main Character will always Feel Bad for him, so fuck him. It was never about him anyway. He just existed to be Victim, making the whole thing an extremely shallow and self-serving piece that may well have been someone trying to feel better about their own past through uncreative expression.
What a waste of potential.
