I found it to be weird, long, and pointless. Can't we just light the torch, have a short speech or two and let the athletes parade?
Even the notoriously left leaning New York Times wrote:
The ceremony, too, reflected the deeply left-leaning sensibilities of Mr. Boyle. It pointedly included trade union members among a parade of people celebrating political agitators from the past, a parade that also included suffragists, Afro-Caribbean immigrants who fought for minority rights, and the Jarrow hunger marchers, who protested against unemployment in 1936.
