Actually, so many of the dings and dents from 90+ years of hard service and occasional re-arrangement are gone, I do find it is significantly improved, ie less of a hell-hole.
The kindest I can get is to say it's a fairly faithful, but not creative, restoration of what was never a particularly gorgeous place. There is still so much disruption and unfinishment in that area that I'm keeping my mind open.
Possibly the choice of colours and materials just wasn't good in the first place. Certainly, bringing back all the wood trim is interesting, but the painted-dark wood trim is nowhere near as charming as the dark-stained original woodwork must have been in the station's youth. There has been little attempt to make better use of space and manage people flow at the gates, but Union was never well suited in that regard. I'm old enough to remember when there were long lineups for a single Rapido (and I can almost remember Pool trains, from the previous era) that extended from the lower gates all the way back up to the Great Hall. Maybe it's fortunate that trains are shorter these days ;-). I would have put those video boards for the queues at the gate doorways, as they were back in the day. VIA is incredibly clumsy at crowd control!
I agree it's a pretty good textbook on "how not to do heritage restoration". One shouldn't retain old materials and surfaces if these are worn out or can't be matched to new stock. Put the authentic bits and pieces in a museum display and replace them with new of like kind. The attempt to retain all that old tile was ill advised.
