Duplass Brothers are
less accessible than the Wachowski brothers? Not in a million years.
Their films could not be about more ordinary people, with ordinary lives, doing ordinary things. If there's a barrier to accessing their films it's certainly not the subject matter or the style. I would put them right at the top of the list.
Operating in the sci-fi genre alone puts the Wachowski's in less accessible territory. Pile on the philosophical (or pseudo-philosophical, if you're a critic) ideas they explore, and the law-breaking physics of films like The Matrix and Speed Racer, and you're in a place many people have no interest in going.
Someone just wants to take a dig at Matrix fans for thinking they're deep when they're not. Whoop dee doo.
