A bunch of suburban friends huddle inside their house after a lunatic with a pickaxe crashes their party and kills their friend. Before long, they're at each other's throats in some hilarious ways.
It took me up until the 20 minute mark to really get into Garden Party Massacre. The humor and performances take some getting used to. Not every performance hits the mark every single time and many of the comedy bits fall flat, but when it works, it works really well and there are enough genuinely funny moments to make it a worthwhile watch. Even better, the film takes some really insane twists and turns right as it's starting to wind down into "been there, done that" territory.
