I think this video is also nice because is fills in the spaces around the period covered by Anne in her diary, particularly what happened after the Franks were arrested and Anne could no longer write. It is important for people who have only read the diary itself to become aware of these other events.
On the other hand, no video (even the best of them--Anne Frank Remembered) can presently compete with the quality of written material out there. There are so many excellent books covering every segment of Anne's life that it would be a shame for someone who is truly interested in Anne to limit themselves to this video.
