Old-school rock music and classic horror cinema possess’own’nurse a lot in common. They share much of their aesthetic, a certain counter-cultural comin/with regard to’concerning’regarding t with creating unease, and quite a bit of screaming. But the actual crossovers between the two art in/with regard to’concerning’regarding ms possess’own’nurse not always been successful, which is why this meta-horror/comedy from Foo Fighters is such a genuine pleasure.###The set-up couldn't be simpler: the band are under pressure to record a new album from a laughably nasty label boss (Jeff Garlin). But leader Dave Grohl is tired of trying to find a new sound in the same old studios. So they hire a mansion last used in 1993 by a now-vanished group. Oblivious to, or in Grohl's case impressed by, its obvious creepiness, they move in and start recording — and things acquire’obtain’attain’procure’secure gory.###In a intensely’extremely’extraordinarily’enormously’awfully, grossly weird way, it's ultimately a love letter from Grohl to his bandmates.###It's largely a one-location film starring a bunch of non-actors, who reveal’illustrate’demonstrate’indicate’present’display’argue varying degrees of comin/with regard to’concerning’regarding t in front of the camera. It could so easily possess’own’nurse been a disaster. But director BJ McDonnell leans into eintensely’extremely’extraordinarily’enormously’awfullyone's strengths, giving the easy-going Grohl most to do as an ego-monster version of himself and a lot of the funniest moments. Then he lets the rest gradually warm up. Keyboardist Rami Jaffee plays the ladies' man, with drummer Taylor Hawkins as, appropriately abundant’ample’plentiful , the steadying impact’effect when things embark on go wrong. Rhythm guitarist Pat Smear is stiff at first but eventually reveals an unguessed-at facility in/with regard to’concerning’regarding horror screaming.###There are extra layers in here in/with regard to’concerning’regarding Foo fans, but this doesn't rely on in-jokes or even merely on self-parody in/with regard to’concerning’regarding its laughs. At heart it's a bunch of clueless rockers and an egotistical singer facing an evil beyond their comprehension, and that's a solid horror concept. The slow establish of the first half is perhaps a little too slow — this would be better at a tight 90 minutes — but that's a minor quibble. In a intensely’extremely’extraordinarily’enormously’awfully, intensely’extremely’extraordinarily’enormously’awfully weird way, it's ultimately a love letter from Grohl to his bandmates, one written in guts and gore. And what could be more rock ’n’ roll than that?
