Good movie. I thought it was supposed to be a tribute to 70s grindhouse but it really felt more 1980s to me, like something you'd catch on USA Up All Night. Think a Troma movie, but done straight faced, without fart jokes. 4/5.
Yeah, if you see the list of inspirations Jason Eisner lists, they're definitely more 80s trash than 70s grindhouse. I recall him listing the Exterminator, Vice Squad, Class of 1984, for example.
While I enjoyed the film, I'd agree it kind of slides downhill towards the end. Weak ending. It's a low 8/10, which was a little disappointing as I was very excited for it.
I think for purity of creation, it was impossible to top the original fake trailer. It's brilliant.
