I think that current Metallica is shhit now too but, to be honest, I went to see them a couple of months ago in Electric Weekend Festival in Spain and they rocked...good set list, good vocals (accepting that the old Hedfield will never return) and great sound...only pissed about Mr Ulrich: he tried to do things that had nothing to do with the songs and his attitude wasn't good enough.
AC/DC would be more than OK for me.
And...for those who say that those bands would only bring people to see them...well, this has been my first time at WOA and, to tell the truth, we didn't care about the bill, me and my friends had always born in mind that some day we would go to WOA and I'm sure we will be there next year again, no matter who is playing, I will be enjoying 10-15 gigs at the least, surrunded by metalmates and drinking (warm) cheap beer...what else would I wish to be happy?
By the way, I'm new here, hi to everybody!!
