Quentin Tarantino is basically a puerile immature man-child obsessed with the hyper-violent, the hypersexual, and racial tensions. And for what it is, it's good. Some of his films are very good for what they are. Pulp Fiction being his best. Reservoir Dogs being next. Most of the rest is massively overrated and built more upon his star-power and reputation than actual quality filmmaking. Seriously, Django Unchained and Inglorious Basterds are mediocre as fuck. But we live in an era where hype and past popularity is more important than the actual quality of current projects, at least in the film industry. People want violent, sexual, mindless entertainment, even better if borders on the controversial especially in a racial or gender context, and Tarantino is perhaps the gold standard here.
Anyways, he's clearly very good at what he does, but let's not portray his films as something they are not. They can certainly be appreciated for what they are, but trying to elevate them into masterpiece status is pretty farfetched.
