It really is hard to compare artist's in their 60's playing power metal than when they were in their 20's with all that zeal and energy.

I know everyone wants to hear the Dime of old and I get it.... but those days are gone. Plus no one is going to cop Dime to a tee especially Zakk. For me it's good to hear the songs one more time even if it's Zakk playing his tribute to Dime even though it's more than likely is a money grab but I don't think it's on the level of money grab like Rush's ticket prices but I could be wrong.
I saw Pantera one time in 2001 on the Reinventing the Steel tour and that performance was pretty lackluster. They had Dime buried in the mix and the overall mix sucked. As of 2001 the band was beginning to come apart about that time so I'm sure that had something to do with the subpar performance.
It wasn't the same Pantera of 1990-1997 IMHO.
