Two teenage metalheads get together and form a band. When they play the notes written on ancient notes that they acquired, they accidentally unleash an evil over their town. It's now their job to fight the evil demons before they become one of them.
"Deathgasm" is a gore-soaked horror/comedy from New Zealand, so naturally people are quick to compare it to Peter Jackson's early work. I'm not sure those movies would be the first that I compare it with, but it is definitely made for the same fans. I'd say it fits better into the group of zombie splatters that came in the early 2000s - namely "Undead" and "Dead & Breakfast", mixed in with something like "Tenacious D in The Pick of Destiny".
The movie is about a young metal fan, Brodie, who has to move to his Christian uncle and aunt (and their asshole of a son). He doesn't fit in at school so he hangs out with the "nerds". But soon he meets another young rocker while browsing a record store, and the two decide to start a band. One night when they're out for some shenanigans, they steal what appears to be ancient song notes. When the band finally attempt to play the song - hell is unleashed on the small town.
One of the crucial points that made this an enjoyable movie for me was that the metal fans seemed more real than the majority of the movies that has "the weird goth kids". The movie does push for some of the stereotypical bits, but mainly it seems to be about a group of people who enjoys the music - and sometimes that includes a few great jokes. Simple stuff like Brodie eating ice scream with a girl from school, while wearing full corpse paint and spikes. Or when the band records a music video akin to Immortal's silly wood adventure video. It might be exaggerated at times, but it's not all about being cool and gloomy, and that's a huge plus. But I suppose you can't make a movie about metalheads without falling into some of the classic traps - but this is a case where I forgive it.
Now, gore is important in this movie, because we came for gore and comedy. There are few moments where we're let down by the gore - quality and quantity. I wouldn't class it as the goriest of its kind (especially not if you want to compare it to "Braindead"), but it is doing the splatter/gore part as expected. Gore effects are generally great, or at the very least entertaining, throughout the movie, but some demon effects are slightly lacking. Especially the "main" demon that is resurrected towards the end - it just looked goofy with its big head. But this is a minor complaint in a movie that is generally a perfect weekend movie for horror/comedy fans.
It's been a while since we got a movie that hits the right places for a gory horror/comedy. They are usually lacking in one or more of the departments - and usually it's the comedy. This one delivers it all and that's a good reason to watch it. It won't fall on a list of favorites, but it fits into the same company. If you enjoy blood and gore, metal music and comedy, then what more do you need? Jason Lei Howden has succeeded in making a movie that is one of the best of its kind in the past 10 years.
