Jeremy Heilman’s review published on Letterboxd :
Dismal. Four bandmates in a heavy metal band (for no reason whatsoever are they in a heavy metal band) take a day job at the local insane asylum. During a blackout, the patients rebel, taking out the hospital staff. Half of the run time here takes place before the run-time, and it’s excruciatingly slow-paced. After darkness falls, the film only offers a series of scenes in which people run around in the dark hitting one another (you’d be hard pressed to tell one character apart from another). The last fifteen minutes are finally gruesome and mildly effective, but it’s far too little too late. Apparently, IFC picked this up for a Pay Per View release. That’s probably more than it deserves.
