I highly anticipated this film being release but a mediocre film (most were pointed out already by others):
1. Loosely strung together scenes - was anticipating more behind-the-scenes, personal footages vs. racing highlights (e.g., how he was able to rebuild Ferrari as a team, not just "oh Schumi stayed late, was caring and a good leader"
2. I would imagine most of the viewers are racing fans and most of the info, if not all, are already well-known to racing fans
3. Delving a bit more details around his "selfishness" (right, wrong or indifferent) would have been interesting - e.g., smiling / celebrating on the podium in Monza after Senna's death, "parking" his car during qualifying in Monaco - was interesting to hear Damon H basically saying "I may have done the same, if I was leading the championship"
4. No interviews with JPM? :-)
Not sure the filmmaker had enough personal footages, etc but (as someone pointed out) the older Senna certainly had more insights and seemed more like a documentary vs. racing highlights.
