Kudos to the UK for hitting it out of the park! The opening ceremonies were extremely creative and unexpected, especially the final torch run and it's lighting. It didn't hurt that my all time favorite band, Pink Floyd, was on the PA system as the torch was being lighted. Congrats to all you Brits on the forum here. May the rest of the Olympics go as well as the opening.
Only nitpick, I'd like to have seen the Floyd on stage. Beatles, meh. Pink Floyd .
I liked the opening video following the Thames down. The opening show was interesting but as my wife commented, it felt like they were trying to shoehorn absolutely everything in there and it kind of dragged. I liked the flying rings coming together.
