I did like the Senna film, does show how corrupt it is also!
I was shocked to discover just how corrupt it was back in those days! Jean Marie-Balestre was the big cheese, and the quote that sticks in my mind was "The best decision is my decision".....The absolute farce after the 1989 Japanese Grand Prix showed the kind of dealings that went on behind the scenes. Mind you, some of the dodgy dealings that go on today with Bernie the Bolt probably aren't too different.
The other thing that has really ruined F1 is track design. The guy who builds all the circuits nowadays (Tilke) repeats the same blueprint over and over, which does provide a good spectacle, but does not provide for good racing. Take a track called Hockenheim. It used to be three long straights through the forests of Germany, with three tight chicanes and a stadium section, which offered plenty of overtaking. In 2001, the track lost its forest straights, where all the overtaking happened, and the circuit was drastically shortened to pretty much just the stadium section. It's had it's soul completely ripped out of it, because it became a tight and twisty track, and with the aero designs on the cars in modern F1, they just can't follow each other closely enough to overtake. Throw in the modern tyres which burn up so quickly, and it's not racing anymore, because none of the drivers ever drive to the limit, they're too concerned about looking after their tyres to drive on the edge.
Hmmm, I appear to have gone on a little bit of a nostalgic rant here. But I'm a massive fan of F1, and over the last ten years or so it's gone from a hard graft racing series to a freak show. The only man who seems happy with things is Bernie Ecclestone, because he makes so much money out of it....
