Here's another review of the opening night, by John Aizlewood for the Evening Standard:
Having seemingly resolved both their internal strife and external demons, as well as coming to terms with being equally silly and spine-tingling, Bon Jovi have become the Rolling Stones of the 21st century.
And a reasonably positive but not glowing review of the second night by Simon Hayes for the Wharf:
But there was something slightly lacking - perhaps it was just the fact that the show, for all that it was well-produced and executed, just didn't quite have that spark of greatness. Not that the 20,000 or so fans packed into The O2 were complaining. They came to commune with their heroes and they weren't disappointed.
