I have now amended my review to include an evaluation of the Second Screen function as experienced on my laptop.
The short version is that there isn't a lot of content there, and what is should have been part of the Blu-ray rather than getting ported off to an online server. There's a good idea in there, but doesn't need to be played out on other platforms. Also, when the laptop interacts with the player for Second Screen, the remote function goes wonky and the movie will pause and start up at odd times that cannot be what was intended here.
It is my hope that this idea is revisited and improved before the next Second Screen title, Cowboys & Aliens, hits store shelves in two months. Otherwise, you're just as well having the material on the Blu-ray itself to keep things simpler.
