Two climbers spend multiple years planning to scale a rock face.
The Dawn Wall (on UK Netflix) was excellent. In my opinion it’s a much better documentary than Free Solo (2018) as the climbers could articulate what and why they were doing what they were doing. Plus the journeyman-like slow ascent lasted longer (in real life and on-screen) and was arguably more dramatic and exciting than the virtuoso display of technique shown in Free Solo. I liked Free Solo but this is much more gripping in my opinion. I could engage with the human element much more.
