I saw the first show of the reunion with Roth (and Wolfgang), in Charlotte, and it was amazing. No, he didn't sing every word, yes, he did his "Dave!" schtick. But honestly, in the moment, I didn't miss Michael Anthony even for a minute (and I get he's good; I saw him in a club with Chickenfoot and he was solid as a rock).
Respect to those that have a different opinion, but if you're in for two-hours of sweaty rock and roll, good ole fashioned arena show, you can do a LOT worse than Van Halen. Mike Anthony is a big boy, he can make his own decisions; I don't feel bad for him at all. Not that E/AVH have been perfect (I still don't understand what happened with the artwork fiasco) but it's THEIR BAND. I don't begrudge Ed wanting to play with his son, even for a second (and his kid is GOOD).
I don't know what that looks like in 2019 - I personally don't think we'll see Van Halen ever again, not sustained - but I think some of the criticisms aren't fair in that they don't account for the intent.
