There's always going to be folks that will never be pleased, just the way of the world. If its for 9 DeKalb or 175 Park or 270 Park, some just will never like it. At times, it could also be a matter of letting it settle in, as opinions do change. Or it could also mean that they have no idea what they are talking about but oh well, this will rise, and be glorious at the end of the day!
Just look at those idiots in the community board meetings. Some weren't a fan either. And not just for this but for other projects. Thankfully they are just advisory and not the overlords of what gets built. City would look like garbage if they had true power.
