Marian Dora's 'Cannibal' is based on the real-life case of German sicko Armin Meiwes, the Rotenburg Cannibal, who killed and ate Bernd Jürgen Brandes, the willing 'flesh' he found via an online forum. Sparing no detail in its depiction of the gruesome crime, the film is one of the most gruelling viewing experiences I have ever endured, easily rivalling such disturbing works as August Underground Mordum and Aftermath.
Those who successfully make it past the film's scenes of man-lovin' will be confronted with some of the most disgustingly realistic and gut-churning scenes ever committed to film, including a penis severing guaranteed to leave men squirming in their seat, the nauseating sight of the almost-dead victim vomiting and emptying his bowels as he is carried to a barn for slaughter, the prolonged butchering of his corpse by his naked killer (including time out for a bit of entrail fondling and stump licking), and the final consumption of the meat.
While it's hardly what I would call an enjoyable experience (it certainly won't be getting a re-watch from me anytime soon), Cannibal is an effectively disturbing piece of no-holds-barred film-making that succeeds in reminding the viewer what a messed up world we live in. For being so balls-out (rather too literally at times), I reckon it's gotta be worth at least 7.5 out of 10, rounded up to 8 for IMDb.
