He's only considered original in ways that only film students give a damn about, and because the genres and styles he rips off are largely unknown to the general viewing audience (often for good reasons on account of them mostly being filled with crap).

I've got nothing against violence, but there should be a point to it and it should make sense. Characters should not randomly do aburpt heel turns just so there is an excuse to prolong the film and shoehorn another half hour of violence in there. Violence should be about establishing the character or marking a definitive point in a character or plot arc. It should not be the reason for the scene or arc. Violence is to a Tarantino film, versus a Resident Evil film as sex & nudity is to a porn film versus an HBO show. Tarantino's plot and character arcs in his last two movies exist to set up gratuitous violence, in exactly the same manner and reasons as they exist to set up sex scenes in a porn film (or even a Skinemax flick).

Uwe Boll has never disappointed me, but that is no reason to put him in that group.
