Movies Anywhere is a step in the right direction for consumers but certainly not the end of the road in terms of needed improvements. It is a better way of doing things than Ultraviolet, which felt more like a half-hearted attempt from the beginning.
Movies Anywhere is the expansion of Disney’s own “Disney Anywhere” service to include movies from a handful of other movie studios, and to connect your unified library to all participating services. It is free to use and you don’t get any ads or previews (like the DVDs) while watching the movies.
