Having watched most if not all documentries about senna and being an avid fan of formula one since i can remember, I was not really impressed too much by the film, one aspect that it did not seem to portray is his dedication and commitment to his driving, his sheer work ethic in fitness, team work with the team, and his desire for knowledge about everything to do with his race car. it spread everything too thinly imho.
On the day, I was watching bbc2 and saw it all, then switched to eurosport as the bbc cutaway, they showed the aerial footage the same as the fil, except I remember a zoom in even closer for a brief second on his head judder that is imprinted on my mind.
