https://www.imdb.com/title/tt8058874/ Rated R for bloody violence, pervasive language, some drug use and sexual references I'm surprised there's not a thread for this one yet, so here it is. I would strongly advise NOT to view the trailer before seeing the film, because it will literally ruin the entire experience. I don't know why they chose to reveal and spoil everything in the trailer... but they did. Even the "Overview" on the Blu-ray/DVD releases has a key spoiler in it, so don't even read those first. It's really not recommended to know too much about the film at all before viewing it... but I will try to do a brief synopsis without any spoilers: The entire film takes place in 1988 focusing on three "Metalhead" teenage girlfriends heading to a Metal concert...soon to get mixed up with three "Metalhead" guys also attending the same concert. A beautiful 80's furnished mansion and Johnny Knoxville later appear. And that is seriously about all that needs to be known in advance of viewing the film. Also, whether you are (or are not) a Christian... the film will probably piss you off early on until the plot begins to flesh out and certain things become known. The film is NOT really about "devil worship" though, I will say that. So if that brief description doesn't sound interesting, you probably will not like it. And if you do view the trailer first, prepare to be disappointed later. I thankfully avoided both the trailer and the Blu-ray overview/synopsis, and was pleasantly surprised by this one. The film did piss me off at first, until the later plot twists when things started to gel together. What other film would have a Mercyful Fate "Black Funeral" song, a Belinda Carlisle "Heaven Is A Place On Earth" song, and a T-Pau "Heart and Soul" song? Yes, it gets bloody. No, there is no female nudity. Yes, the language is strong throughout. As for the Blu-ray itself, the A/V quality is excellent. The only features are a Featurette and an Audio Commentary with the Director and Writer. I found the Commentary quite informative, as there were a lot of further stories and such revealed, so if you do enjoy the movie it's well worth listening in on.
