I would have traded the whole internet thing for more of the rural part at the beginning. I thought the Hobbit set was gorgeous and charming and wish they'd made more of it. They could have used the 40 years of British music from the internet section for the parade of nations and just skipped most of the boy meets girl and has a party stuff.
But overall I enjoyed it and always appreciate all the effort and endless hours that the organizers and volunteers spend on the ceremony. I particularly liked having some of the people who built the stadium there to greet the torch - a nice and original touch.
I didn't mind the kids, but I would have preferred if they ran around the arena with the torch and then met up with the mentors and the mentors lit the petals.
Loved the flying nannies and the whole children's literature segment.
