I don't think I've ever seen such am empty open world.
Visually it doesn't look terrible, clearly a large amount of effort went into the detail of the world and it's design, but the failure seems to be on the design of the game and what the hell to do in it.
That long walk to the objective and not encountering a single thing.... Yikes. I'm not one for map barf but jesus.
