It's a context situation; this one is more functionally bad than aesthetically bad (for me, I can think of beautiful buildings that are functionally bad and aesthetically horrible buildings that work well as parts of the city).
In this case, the new street was dropped in the middle of a compact neighbourhood of small houses on small lots and a few lowrise apartment buildings. It's a top-notch walking area with gently meandering streets, lots of green space and hidden spaces and interesting dead ends. But it's not served at all by transit, so a couple of newer private cul-de-sacs were built to serve cars with garages lining the main floors. This development took that trend to its most extreme and Vince Ave's street level is basically a parking lot. Aesthetically, the houses are just grey and bland (the interiors of the original phase had an odd, institutional finish). It's the jarring contrast with the rest of the area and the total failure of the process that earns this street my neverending lack of love.
