Given it a quick go and first impressions are very good. The demo was cool but didn't really win me over as it was mostly a demonstration of technology, whereas in the full game I've only been introduced to one character and the first major thing that happens to him, yet I'm already completely invested in his story and found it hard to stop playing. The whole opening sequence is pretty powerful too.
The gameplay can hardly be considered taxing, yet it's somehow completely engaging — even when the action scene consists of little more than frantically checking your pockets or walking through a crowd.
