I don't think she half assed it at all. o_O You just said yourself, Hikki isn't a "glam" girl, so if you were expecting something like an ARENA TOUR from Ayu, then you were sorely mistaken from the beginning.
But anyway, I think she did exactly what she set out to do. She wanted to create a show with a warmer atmosphere than usual and she basically projected In The Flesh into a much larger venue. I thought it was a great concert. (:
