Every rights holder having their own service has killed a lot of the convenience because you'll now need several different services to go through an entire TV show, for instance. And also because all services other than maybe Netflix have garbage software for your various devices. Because every service also has to support 8 different platforms. Video playback and scrubbing is buggy and laggy, the GUI for finding stuff is sluggish. On one service(I don't even remember which, they all blur together in my head), I tried to watch some House MD and half the episodes were missing the English audio track.
