“When the Kimmel programs the plaza and streetscape, as it does with festivals and summer solstice parties, the vibe is superb. … But when there’s nothing going on there, as is the case many daylight hours during the week, it’s just you, a security guard or two, and the psychic tumbleweeds. To have Center City charged with workers, shoppers, and students as the Kimmel sleeps is an oddly squandered opportunity at a time when the arts are looking for all the friends they can get.”
