Among the reasons, they cite the ever sliding price point of entertainment.
A group of directors including folks like James Cameron, Michael Bay, Guillermo Del Toro, Robert Rodriguez, Peter Jackson and more have written a letter calling to stop Premium VOD content from happening. They raise some very strong points, but there's no telling whether it will be enough to put the brakes on a project that television providers are greatly in favor of.
Many of the arguments are what you'd expect, but the letter brings up a few things that might not have been immediately obvious, like the ever decreasing cost of DVDs, Blu-rays, and on demand options.
"History has shown that price points cannot be maintained in the home video window," says the letter, "What sells for $30‐a‐viewing today could be blown out for $9.99 within a few years."
