I'd say definitely the most disappointing supertall in the world. But not sure if it's the worst, maybe there's something more worse than this. But I think a city the caliber of Houston needs an awesome supertall.
I live in Houston, and except for it's large size, this building is very plain and boring compared to large towers in other cities. The building's exterior needs to be renovated. So it's the tallest five-sided building on earth... who cares? It's architecturally uninteresting. It's as if the architect put no effort into its design... I could have come up with something better. Maybe if it was the ONLY building in Houston that looked this way it wouldn't bother me as much, but the majority of large towers in Houston (with a few exceptions) are almost as plain... there's too much blandness in Houston's downtown skyline! The Medical Center Skyline is way superior when it comes to architectural design, and uptown/gallery is better than downtown also.... if the buildings in those 2 skylines were twice as tall and in downtown, Houston's skyline would rock.
