So the pilot for Revolution is available legitimately online now (only in the the US).
Watch it NOW
What I don't understand is why the world looks post apocalyptic? The loss of electricity would cause things to fall apart somewhat, but it should not mean that people suddenly forget how to make technology work.
Are the producers aware that the industrial revolution began almost a century before we started using electricity? The presence of fire means that these people are capable of boiling water and producing steam. Does oil and coal suddenly no longer burn? Instead of Chicago looking like an episode of Life After People...it should look like it did in the 19th century. We should see rail roads and lots of smoke stacks.
Revolution could be the ultimate steampunk adventure...but its not for some reason.
