The original Guinea Pig series from the 80's were more shocking than the American series. They are similar in many ways with hardly no dialogue and over the top gore. I have seen several reviewers compare it with or to Human Centipede 2 maybe for the fact it's black and white. The difference I feel is Centipede 2 could not have been made in color the special FX were too good. This films FX are sub par. With that said I did enjoy it somewhat for what it is. I just can't for the life of me tell you what it was. Some enjoyed the score I found it annoying and tedious. The film overall made no sense and perhaps that's what makes it watchable.
