OK, so it was a rough first night, and we've got to expect some hiccups, though perhaps this was a bit worse than what we would expect from a band like U2.
Regardless, here's what I think:
-They should totally play up the entire space angle/theme - this is a great idea and no one else is doing it. They've got the claw. Get into it. Totally over the top. Maybe add a character or two? I was really hoping for that this time since I believe Bono to be an excellent actor - he should take advantage of these skills!
-Breathe should NOT be the opener. I love this song - my personal favorite from NLOTH - but no way does this fit as the opening song. What they should do is play FEZ over the speakers while they come out and then go crashing into Being Born as the first song. Imagine Bono's yelling being the first thing you hear from him. That moment would be absolutely incredible.
-Finally, it's time to drop With or Without You. Just let this song die. There are plenty of other "classics" that fans will be just as happy with. This song has not sounded good live since the JT tour (Zoo TV was OK...).
Other than that, I really liked what I saw/heard. There is a lot of potential with this tour - just like with the album - they need to take advantage of everything they have going for them right now...
