TVNZ review of the NZ DVD release here :

“There’s a lot of gore in this outing and that may put some off but as a well researched horror which is based on a degree of fact, it really does offer something a little different to the genre and may impress more than you’d initially expect.”

- Frustratingly for a DVD review  it doesn’t including any info on the 1 hour behind the scenes documentary, edited by yours truly.

 

And another from Cinemarvellous.blogspot.com:

“”The Devil’s Rock” is an effective, gory and devilishly fun hidden gem of a horror movie.”
