Well I'm one of the few 'yes' votes on this, so I may as well post my thinking here. To me, Tarantino is as overrated as they come. Looking over his director credits and outside of Reservoir and Pulp, Kill Bill would be the only film I liked at all.
[*]Reservoir Dogs
[*]Pulp Fiction
[*]Four Rooms
[*]Jackie Brown
[*]Kill Bill (I & II)
[*]Grindhouse
[*]Inglourious Basterds
[*]Django Unchained
Every other film, including Basterds, I just remember rolling my eyes throughout. Something about his movies, and the dialogue, makes me just picture Quentin on the other side of the camera chuckling to himself all smug and self-satisfied like he just shot the greatest thing ever.
Everything he does just feels so narcissistic and self-indulgent to me for some reason, like his personality comes through in every single scene, and I can't stand the guy so I can't stand his movies. I realize that's probably just my own baggage that I'm taking into the films, but still, that's where I land.
To me, I think his most interesting work was when he was first starting out and had this ingrained sense that he needed to prove himself. At some point, I think his ego and his success collided and he became satisfied that the world knows what a phenomenally gifted filmmaker he is... To me, this has taken the edge off of his game. He seems to have gone to more of a "everything I do is gold, so I'm just going to go play in the sandbox again" approach... Everything he does gets progressively less interesting to me.
The other possibility is that I enjoyed his movies, and his style, when I was in my early 20's but now that I'm older I've just outgrown him. I don't know. Either way, I vote 'hack' but only in the sense that he's overrated. He's not really a hack per se.
