There's only two complaints I have about the set, based on the shows I saw ... and they are really minor:
1. Opening with BD simply does not work. The stringray intro is great, but then there's that kind of awkward pause and BD is a great live song, but not as an opener. U2 shouldn't rely on crowd pleasing classics and old songs to open the show. Many might have hated Breathe as an opener last year, but I still prefer it over BD. At the moment I'm thinking Glastonbury would make a very good opener. They should definitely think this over and get some fresh stuff out there after the intro.
