Well, when the movie is in theather, there are rarely good quality (non-cam) torrents available and the screen is usually bigger than at home, but it might not be a factor, depending on the viewer or the movie.
But it's true when it reach DVD, you'll still have to watch the anti-piracy ads.
Interestingly Netflix et al skip the anti-piracy garbage and excluding the miserable UI actually do a good job of making "pick movie -> watch movie" as convenient as torrenting.
But still, I've torrented every DvD I own and the discs rot in the attic. I never cared about the extras anyway time to watch is ~a hundred times lower.
