Gmood,
Some people like to own a physical disc (Blu-Ray, DVD product). Next today Blu-ray still offers the highest in picture quality with 1080p and the ability to play the full Rez loss less digital surround Codecs. They also give you a lot of added content from just the movie. But yes for so called rentals a hard drive setup is a good way to watch just a movie if that is all you want to do and do not really want to have a physical disc to keep.
