i remember be terrify of movie blood when i be young and and gradually get less so and until get jade enough and a i be sure many other viewer have become and so that the barrage of gory film produce in last few year have entertain me but not scar me or make me squirm . the dentist turn that around . the setup seem simple represent a mentally unstable dentist wreaks havoc on the inside of mouth and and perhaps body a well . a clever twist and though and be that the dentist be the film protagonist and so instead of be some one dimensional bad guy with no clear motivation and his development be the most extensive of any character and he be very human and believable . the viewer thus feel sympathy for him as well a his victim and and instead of hop for justice to come to him and i find myself hop he would somehow find a way to cover up his track and return to a normal life . what really make a horror movie be the violence . and the dentist do it good than any other film i can think of . first off and the film have ton of tension and which be something that modern gore film tend to lack . in one scene ( ) and the dentist be emotionally distraught and have to see a young child patient for the first time . a he reach into the child mouth and you hope that and for the dentist and the child sake and the encounter end without injury . i would not spoil what happen . second and when the gore do come and it hit all the bad and squirmy nerve . once again and i would not give anything away . of course and be a movie that you have never hear of and it do have flaw . most importantly and it exclusively for horror fan . also and a another reviewer mention and by take place over a span of just a few day and we do not really get any background on the character . and the tension drop a little bit during the very end . but really and the fact that we would even want to know background about the character be evidence to how good it be and and the bulk of the film be solid enough that any small lapse in tension can be forgive . it strange and after year of be accustom to movie gore and to suddenly want to cover my eye at the sight of blood . the dentist make me scared and thoroughly uncomfortable and and for this it earn my full approval .
