Just finished watching last night. I enjoyed it although I thought it was less insightful than the first season. Perhaps that was the increased number of teams involved, or just that people were more cautious. I dunno. The part about the F2 crash was handled excellently I thought.
What I found really interesting was how you could see how the contrasting cultures of the teams led to their relative success or failure. Steiner is hella fun to watch, and I suspect he's the one the principle I'd most enjoy having a beer with (even if I'm certain he'd mock me for not speaking German properly) but you can see how he leads to a culture where people are stressed and feel they'll be dropped any moment. Ferrari seemed to believe they have a right to win rather than needing to work properly for it. With Horner you could see how he switched from being supportive to people's faces to coldly ditching them behind their back; like he wants to build the right culture but doesn't have the skills. And Williams just seemed to be floundering, with no idea how to understand their problems.
But then you have Woolf and Mercedes who really commit to the idea of looking for solutions not blame and supporting people to be the best and you could see it in the way everyone they talked to behaved as well as their successes on track. Yes, a lot of its about money, but you could really see how their culture has Mercedes the absolute team to beat. Woolf deserves a heap of credit for that.
