One of my favorite feelings watching a film is one of "You can't do that!" or "Oh my f-ing God they went there!". I felt that nearly constantly as this wildly complex, sophisticated and consistently hilarious Sci-Fi epic unfurled before my eyes on screen.
I'm tempted to call this a satire of Sci-fi action films because of the complex backstorymythology, deliciously ridiculous chainsaw wielding character and most of all the tortured lead having the worst of all possible days even before he enters the titular mining facility full of extraterrestrialprehistoric beasts whose "teeth have teeth"...but it's so much more. The earnest love of the genre and the wildly unique world this film explores permeates every scene. The humor often comes at the expense of genre tropes, but the insane plot actually holds together and delivers a wild ride and satisfying conclusion with true pathos.
On top of that, it delivers a powerful rebuke of runaway capitalism pitting innocent prole miners just trying to live their lives against lunatic rich owners using them as pawns and often as figurative and literal sacrifices to fulfill a prophecy of their own exclusive religion.
No question the budget is low, but the green-screen compositing is shocking good and the expansive and eclectic mix of CGI elements sourced from the internet (as the long credit roll, an event in itself, details). I particularly enjoyed the sequence where an innocent person is immolated in an elaborate ritual with devotees in masks and robes against the backdrop of an innocuous suburban subdivision.
This is a wildly crowd pleasing film that will delight genre fans and even those who dislike Sci-Fi movies. If this doesn't develop a rabid cult following the Earth deserves to be overrun with Dinosaurs from another planet.
