It would be pretty hard to be bored watching this as it has plenty of variety and unexpectedness in the content. It is well presented and the cast is also an interesting mix.
An interesting take on the story. The production values are fine and there is a fine trio of talented performers in Peter Capaldi, Tilda Swinton, and Hugh Laurie in reasonable form.
The concept of the documentary was fine but it just meandered so much. If it had to meander I wish it had been done in her direction and spent the time on her beautiful art.
