What a better place for a horror film than the sewer....literally. Dark, damp, putrid, cavernous, rat infested, and psycho infested. From South Korea, we take a look at 2014's "Manhole." Written and directed by Jae-Young Shin, this film is an ominous one with no humor or daylight. For those who like their horror dark, literally and figuratively, this is a special one.
