I agree with this.
I never understood why Diana and the rest of Justice League need to keep appearing when the show is Young Justice. Especially when it seems like they're only there to be useless and outsmarted at every turn in order to justify why the younger heroes are the protagonists.
And looking at Weisman's comments......yeah, I can't say I'm keen on his take on Diana or her world.
This is why I always get antsy when someone suggests DC should just model itself after the DCAU or let guys like Weisman or Bruce Timm steer the ship. Wonder Woman and her world always seems to get the short end of the stick.
