Sarcasm aside, whether a city is boring or not really doesn't depend on architecture.
Seoul and Tokyo have forgettable buildings, but they are ten times more lively and interesting on the street level than a typical beautiful North American city. The small restaurant scene at Shinjuku at 8pm any week day is simply breaktaking, probably more than King W and Yorkville combined. I was so amazed by how vibrant all those small narrow streets are. Even the areas far from the core have retail and small restaurants on most side streets.
East Asian cities, despite their general architectural blandness, are a whole different level when it comes to street liveliness.
