Nothing says "entertainment district" like an 8 storey blank wall that stretches for an entire block.
There seems to be minimal consideration of context. Most people will be approaching this building from the NW corner (at 12 Ave and Olympic way). 12 Ave will be the east-west route through the rivers district. But it puts up a giant blank wall along 12 Ave. Instead, the arena is oriented toward the SW corner (14 Ave and Olympic way). Why? 14 Ave runs straight into the loading docks of the BMO centre. That intersection will never be a major area for foot traffic.
