The subtitles were very accurate and well-placed. The trailer video is only ten minutes, and the full-length is available for purchase. It would be ideal to have a follow-up video, say ten years later, to explore how their national and cultural identities have changed for them and the later generations (their young children).
The video and links worked. The background and lettering made the reading easier. The video has English subtitles, but for the visually impaired, it would help to have a speech option.
