Overall very impressed, I thought the whole thing had wit and poise. Above all it had a degree of intelligence that engaged me, spotting allusions and references all over the place (Pink Floyd's "Animals" album cover recreated, etc.)
Agree though, that "Hey Jude" fell flat. If they had ended as I thought they might, with Macca singing "And in the end / the love you take / is equal to the love you make", that would have been stunning. (Although would have been even better as the close of the closing ceremony).
On replaying it in my mind, I keep remembering aspects that were fleeting and yet jaw-dropping ... Evelyn Glennie leading the drumming, Ban Ki-Moon carrying the flag, the shower of Mary Poppinses ... a mix of big picture and small detail, of deep pride in this country and celebration of its silliness.
The challenge of doing something that would be neither overshadowed by Beijing, nor parochial and trivial, nor trite and sneerworthy was immense.
The Boyle done good.
