Blood Creek by Joel Schumacher (Falling Down, Batman Forever etc) would be a total mess if it weren't for a handful of unusual tweaks.
Starting with a rushed but decent set-up, Nazi occultist Wirth (Fassbender) turns up at a struggling American farm run by German immigrants who are glad of the paycheck the guest brings in each month, but wary of his mysterious interest in ancient runestones. It turns out that his academia hides a dark secret, and we cut to the modern day setting, only for the story to lose its focus. Although it oozes promise by introducing Herny Cavill's lead character with a dramatic scene, the economical script skimps on plot and dialogue. It brings back Purcell (Prison Break & Blade Trinity) as his missing brother with minimal impact and then tries to sweep us up by running headlong into the kind of suspense and horror plot where a bit of foreknowledge lets the director build fear and foreboding in the audience. Instead, we blunder and crash into the situation just like the main characters, and nobody bothers filling in any blanks until a long way in. This kind of technique only works with exceptionally tense direction and committed performances.
In the case of Blood Creek, the performances are just decent and Schumacher is off his game, nowhere near the dripping paranoia and tension of 'Falling Down'.
However, then there's the movie's salvation. When he's unleashed, Wirth isn't just your typical Nazi zombie. In fact he never died at all. Hideous but virtually immortal, he's become a Necromancer capable of raising the dead to do his bidding. This makes for a number of exciting seige scenes where he can send a lethal minion in to wreak havoc while he's kept at bay by the flimsy use of a few breakable runes.
Cue the film's best scenes, as a furious Wirth races to the house time and again, only to get barred at the last minute with a shout of feral fury, as zombified horses and dead locals terrorise the inhabitants.
Fassbender is slightly wasted in a monster movie as he does his best work with tone and facial expressions (see his repressed rage as Magneto in 'X-Men First Class' or his great officer in 'Inglourious Basterds'). However his character's unusually charistmatic movement and behaviour helps elevate what would otherwise be a forgettable B-movie into something a little more watchable.
Directorially it's a bit of a mess, and plot-wise it's like someone took the scenes and threw them into the air, let them land and then assembled a movie. Purcell gets no motivation or character at all except revenge, and future Superman Cavill gets no character but 'I'm a little more noble than him'.
However, still carefully recommended for fans of monster movies, and for those who want an unusual look at character actor Michael Fassbender playing a charismatic monster.
