When I buy new Blu-rays, they don't include commentary from the cast & crew. This was one of the main reasons I bought movies to begin with. Commentary was standard on every DVD 10-15 years ago. Special features in general are lacking in Blu-rays nowadays. Why do they no longer offer this?
What is especially interesting about this, is that studios now will spend upwards of $100 million in promotion and tie-ins with any given movie. Take a movie like Minions, for example. One of the biggest promotional campaigns of all time. But on the Blu-ray, no commentary. Even good movies, like the Peanuts movie, and Zootopia, from Disney of all companies, have no commentary. People now need to buy expensive "art of" books, in order to find any in-depth overview to the "making of" for these movies.
In fact, pretty much every movie that's come out within the past few years has no commentary track whatsoever. With some older movies, they will at least transfer the DVD commentary over to their Blu-ray releases. So why is this? Why have distribution companies ceased offering commentary as a standard feature on Blu-rays?
