There's few things I hate more in the world than filmmakers (or, people in general) that have been criticized extensively precisely because they were true to themselves ("oh no the violence! oh no how sick/twisted") proceeding to tell other filmmakers that they shouldn't do shit their own way because its [insert qualifier]. I don't want Tarantino to stop doing what he does as his evolution (up to IB) proves his own style and metafilmmaking has merits of its own and, you know, its precisely what he is obviously passionate about in the same way Cronenberg has his own themes and interests. And, considering the increasingly media saturated culture the world, for better or worse, has embraced, I think this arbitrary distinction between taking from "real life" as opposed to movies is rather ridiculous, a point that, for that matter, one would think the man that made Videodrome would have no problem grasping.
To be fair though, I imagine it'd get exasperating to have your new movie constantly labelled Tarantinoesque simply because it had some violence.
