1. Every opening ceremony has sucked for every Olympics ever. All of them... Every last one. They're always a sort of in-joke for the people who live in the host country. People outside the country don't get it, and people inside the country think it's a bit stupid and self-celebratory.
2. Yes I love the NHS. It's saved my life on more than one occasion. Yes I think the model should be used by other countries. A health service which is tax funded and free at the point of use, open to everyone... Epic idea, and it works. Did Danny Boyle need to make such a big deal out of it? Not really.
