All epochs of F1 have excited me, and they still do. Occasionally, there are races that appear to be dull and processional, but there is still nothing to equal the sight, sound and paraphernalia of it all.
From the least, to the most, powerful cars, there's always something to produce secretions of adrenaline. I understand the views of armchair critics who moan that it's all boring, but TV by its very nature, cannot capture the unique experience of actually being there.
Some folk get excited by other sports, including cricket, tooty, darts, snooker and the rest.
I can only surmise that they've never experienced Stowe Corner, Tabac, Eau Rouge, Radillon, Tertre Rouge, Druids, Old Hall, Lodge and blah, blah, blah. I used to feel sorry for such folk but, alas, not any more...
