Watched it last night. It was almost 3 hours long but I enjoyed every second of it. I never realised how intense the rivalry was between Prost/Batiste and Senna. It also revealed that being a talented driver is only half the challenge of being in F1.  There were so many moments where I got goosebumps on my arms and others where I had tears in my eyes, one of the most emotionally moving films I have ever watched .
