imagine that you be one of a small community living in a huge abandon hospital after the fall of civilisation . do you a ) fortify a section of the building to protect against attacker and methodically search for useful supply and weapon and food . or b ) elect a useless leader ( who be happy to spend his day bang his woman ) and leave all the hospital entrance open and and not worry too much about food and weapon and since you have plenty of tasteless army ration and at least two gun and a handful of bullet in case of an emergency . if you answer a and then you fully deserve the max rockatansky award for successful post apocalyptic survival while if your answer be b and then pray that civilisation never crumble represent youre clearly not build for life in a world thrown into utter chaos . now imagine youre a member of group of survivor that have be drive to cannibalism due to a lack of food . you and your pal have several people trap inside a large building while they be outnumber and poorly arm and unorganised and and ripe for the picking . do you a ) storm in there and take them all alive ( to keep the meat fresh ) and and cart them off to your lair . or b ) devise an elaborate plan to get one of your people to infiltrate the group and then wait until nightfall and when the building be plunge into total darkness and and take just one victim and leave the rest for another night time visit at a late date . if you answer a and then congratulationsyou have the making of a successful ( and well fed ) cannibal while if you answer b then youre as stupid a the bad guy in tooth and nail and and fully deserve to have your own as hand to you on a plate . full of annoy character incapable of make a decent decision and tooth and nail be a dreary piece of dreck that struggle desperately for a sense of realism and but only manage to bore in the process . whereas recent post apocalyptic effort doomsday revel in it sheer cheesiness but suffer somewhat due to a lack of a thoughtful plot and tooth and nail prof to be the anti doomsday of the genre and take itself far too seriously and severely lack any sense of fun . writer or director mark young script be extremely weak and with it undercover cannibal plot device be neither particularly convincing nor totally unexpected and and there be plenty of banal dialogue to bog down proceeding even far . the direction be also rather uninspired and and with much of the action take place in the dark and the film be a real strain on the eye ( and one patience ) while it also make see what might have be some half decent scene of gore almost impossible to make out . i rate tooth and nail a disappointing 3 . 5 out of 10. normally and i would round this up to 4 for imdb and but thanks to a ridiculous final shot of a cannibalistic vinnie jones gurning maniacally through a window and it get round down to a 3 .
