Pfft. The whole point of a demo is to get people excited about the game and make them want to buy it. If someone doesn't get excited about said game based on the demo, it's not a failure of character, for crying aloud.
To be perfectly honest, I don't think the DA2 demo did a good job of presenting anything other than the new combat system. Picking a wasteland for the opening sequence is hardly going to impress anyone with the shiny new graphics engine, for example.
Compare this demo to the Mass Effect 2 demo (spoiler for the three of you who haven't played it by now)

The freaking Normandy gets blown up, and there's that terrific sequence of Shepherd walking through CiC with the gaping hole above his head showing the planet nearby
