The constant delays and lack of updates are annoying no doubt.
What I do know is I've seen them live 3 times, and loved all 3 performances.
I have to say i have seen GNR live 3 times also once on the Illusion tour with Slash, Gilby, Sorum & Duff and Twice with the new band (Buckethead era).
If i'm honest the original band had that X-Factor of cool that the new band didn't have, but the music was as good if not better at both Shows i watched in more recent times.
I liked the instrumentals and i think Axl's voice is still amazing.
What i would say is i find it funny how many "critics" say they hate Axl turning up late but miss the Rock N Roll aspect of GNR that Slash & co brought. When i first saw GNR with Slash.... the band was nearly 2 hours late on and it transpired over the next few months that they were late coz they couldn't find Slash and by the time they found him.... he wasn't ready to go on. Now how true that is we'll never know.
