Callan Bond’s review published on Letterboxd :
One of the best documentaries I have seen, this movie composed entirely of archive footage (no "talking heads") keeps things moving a brisk pace and tells a very interesting story along the way. The film makers did a great job of picking the right snippets from race and news footage, and overlaying archival narration where necessary (presumably from other programs on Senna), so that as a viewer you're never 'lost' as to where Senna is in his career and what's at stake. The developing rivalry between Senna and Alain Prost, and the different approaches each takes to the sport, is clearly illustrated simply by the clips shown and the sparse narration that is included.
For something I had no interest in (F1 racing), the movie excels in both being engaging from the human standpoint of Senna's character, and in relaying the excitement of the sport itself.
