i just finish watch guinea pig devil experiment . i have to say that this movie and although have very good fx and good then i expect and be not a good movie . i honestly cant say that i enjoy this movie at all . of course it be effective in it way of be a shocking and realistic and twisted 43 minute of torture and but i find it to be very boring ( and not as gory a i hop ) . and also i find that the torturer be very annoy and when they talk and loughed try to sound tough all the time and that ruin it even more ( and im sure there some people out there who will agree with me on that one ) . i have now see guinea pig 1 and 2 and 3 and 5 and the best one out of those in my opinion be guinea pig 2 flower of the flesh and blood . i wont say much more about devil experiment and other than great fx and descent act from the girl and annoy fuing torturer and overall i give it 4 star on account of the fx co they be awesome .
