I don't like Prost's portrayal, I don't like the mis-match audio for the onboards, I don't like the ignorance of Senna's dark side and I don't like how it effectively skips straight to the McLaren story.
There is so much this film doesn't cover and I don't feel it gives a real impression of what Senna was really like (which although thats rich coming from me as I was too young to have known this, its something I have come to understand though opinions of the time and simply watching the old races).
I think its a nice film to tempt people into watching F1 but its sadly not a very good description of Senna at all. The main theme with Senna is the fact he had no problems trying to bully drivers into lifting or facing a terrible accident but he also worried for the safety of F1 drivers and did genuinely care when someone was in peril. Its such a fascinating set of attributes, so fiercely competitive yet caring. The fact that this film does not even portray this is very sad indeed.
Instead, the film basically portrays Senna as a driver who did no wrong and always tried in the face of adversity. It also portrays Prost as being purely political and suggesting Prost didn't have the speed to compete with Senna. While this isn't completely wrong..its not really a fair or accurate portrayal of any of the events or people involved.
While I realise this isn't really a documentary, its more a film, they didn't need to portray Prost this way and they could have easily used the much more interesting duality of Senna's personality instead of the "fallen hero" story they have tried to depict.
Decent film, worthy of showing non-F1 fans but it could have been a lot better and I personally feel its not a fitting tribute to the man. Simply ignoring his flaws is not respect. Respect would be displaying his flaws but contrasting them with his strengths.
If people want to watch something that gives a real feel for who Ayrton Senna was, I refer them to the BBC 1995 documentary as its much more fair and honest and doesn't glorify him. There is also the recent short Top Gear documentary which does a good enough job too (which only serves to contrast with this proper film even more....if TopGear can manage to make a good, balanced piece on Senna, surely anyone can!).
