Sort of how I felt, although it's a great primer for someone who doesn't get the obsession us gearheads have with him.Honestly, I wasn't impressed by it. Perhaps it's because I've seen many a documentary on him, multiple times, and already know what his life was like. It was just the same footage mixed differently and with more dialogue from enough people (friends, teammates, family, etc..) to last a couple of hours. That's not to say it was bad, though. Just kind of stale. There were a few little things I didn't know about, but the gist of it was the same old stuff.
That said, it's great for people that don't often look up Senna stuff. I'm glad Netflix finally included it.
