There is an entire other thread on this before.
They built a $300 million arena and people expected a $500 million arena. Its certainly has too many basic issues (like the congestion at points in the upper deck, putting all the concession stands behind the net in the lower concourse - in Mellon even with igloo seats they were able to wrap some around the corners, the igloo clubs are far far far worse which was surprising). The view from seat is fantastic I just end up spending a lot of my money somewhere else before and after the games, still make a night of it just not quite the same night as before.
- and everyone knows my emotional state towards some of these things so I am not going to say any more on this topic!
