"Biotherapy" is a fairly nasty Japanese gorefest about a group of Japanese scientists stalked and viciously butchered by a creepy-looking alien. This relatively unknown ultra low-budget splatter film is rather well-made and captivating. The gore effects by Osamu Miki are effective and suitably nasty for example the scene where a scientist has his eye pulled out is extremely graphic. There is also incredibly bloody moment in which a female scientist is sadistically murdered by having broken test tubes jammed into her body and the blood is spraying everywhere. "Biotherapy" is not as sickening as Daisuke Yamanouchi's "Red Room" series or Tamakichi Anaru's ultra-nasty "Women's Flesh",but it certainly provides plenty of red stuff for fans of crazy Japanese splatter.
