I think he's done the best possible under modern stadium build constraintsIdeally you could gut each stand from behind and keep the old lady the same toward the pitch, but that wouldn't fix the terrible line of sight issues from too many seats.
Hoping the steepness and tightness of BMD can help hold the atmosphere. The fans are mad too, which helps a lot.
I honestly believe the new place could be a bear pit like Goodison. I think Meis did a good job.
