P2P film piracy, at least for the quality-minded, has a few strong competitive advantages over film streaming. It doesn't have to deal with rights issues, for one, which can present huge roadblocks to film distribution. Films are also huge files and the interests of a streaming platform (low bitrate) are in tension with interests of quality. Even in comparison to physical media--the highest quality release of a film might be from a different market than yours, or there might be many competing releases over time. There might be different factors that are better in one release and other factors better in another release, where the pirated copy can combine all the best parts. It's actually somewhat remarkable how good film piracy has gotten these days for those who care.
