The opening shot of the second trailer is pure genius, it shows the remains of the war - from the crashed X-wing in the front, to the massive remains of the Star Destroyer in the back. This shows us that the days of the Empire is done and  that it has been years since the last galactic war. We then hear Luke saying: "The Force is strong in my family". It continues through the trailer like this: “The Force is strong in my family, My Father has it,  I have it, my sister has it, you have that power too.”
