This was phenomenal! The intro reminded me of the John Carpenter's The Thing's intro with the same repeating beat playing throughout. If I had to make any criticism I would say the monsters throughout most of it felt jarring and took me out of it, like they were powerpoint slides inserted between scenes in the first half or they looked like a devil costume with tentacles. But other than that minor bit the whole thing was spot on for 80s and 90s horror. The monsters and effects at the end were radical. The blood flowing up was an amazing idea and I was so taken in by that!
