The Guard From the Underground - Earlier one by Kiyoshi Kurosawa. Seems to be his take on the slasher film genre, but it already has the iconic style of his most well-known works. As usual for a Kurosawa film, the visuals are gorgeous and atmospheric throughout, with tons of yellowish and sepia tints everywhere. The whole thing has a rather dreamlike, bizarre quality to it from start to finish. Even though the entire thing is for the most part set within the confines of an office building, the way the entire place is presented makes it feel alien, even strangely hellish in some places. The killer is very effectively menacing (dude is TALL) and there's a bunch of rather brutal kills in here. Definitely better than its IMDB rating suggests
