Let's not forget he's an actor, writer and director.
So, you say Reservoir Dogs is good, Victoria, do you mean the writing, the directing or both? Ok, you said "director" so let's just assume you meant "director" and look at his other films purely from a directorial point of view.
Pulp Fiction: Oscar Nominated for best director ... and a truly original film that oozes cool. Won the Oscar for best writer, so it's tough to call Tarantino over-rated as a writer, but we're just discussing him as a director, right?
Aw, shucks, I don't really need to go through his directorial skills for each movie, do I? I mean you've already written off Pulp Fiction, so there's no chance for any of the rest. Oh, even if you don't like the films, you can't say they're badly made.
