The region free copy I got of Zatoichi The Last
was horrible. The video played at a different rate to the audio, and often froze. Just terrible quality.
The third series of Black Books
had no commentary despite the previous two series having commentary on each episode.
Many TV series put out by Showtime
have no extras pertaining to the series. Often times they come with an episode of another series as an extra. Usually something I have no interest in watching.
