As a story, the film is a bit of a mess, with various plot threads that go nowhere and strange non-sequitirs that, perhaps intentionally, have the effect of blindsiding the viewer like a sledgehammer.
The film never really decides whether it wants Jackson's Riko to be the town fool or the coolest guy in the room, and often fluctuates between the two depending on what the scene requires.
Elsewhere, there's some fun to be had in Tom Sainsbury's nefarious but bumbling conspiracy theorist, while talented newcomer Harry Summerfield provides a dash of warmth to proceedings as Riko's softie best mate Rabbit.
The standout is clearly JoJo Waaka as Riko and Rabbit's sometime love-interest Jacinta - the actress, who passed away recently, shines all too briefly here, suggesting a wealth of true talent. It's a shame that Alien Addiction all too often reduces her character to a series of sizeist jokes that feel mean-spirited, rather than just a bit of fun.
It's a structurally messy, blunt and at times quite offensive work. But if it becomes a stoner cult staple in New Zealand in a few years, I certainly wouldn't be surprised.
