Have you started noticing any trends in the movies coming out this spring and summer?
Consider the terrorist attacks (or worse) that hit London in the trailers for G.I. Joe: Retaliation and Star Trek into Darkness. Consider the quasi-military attacks on Washington D.C. in Olympus Has Fallen and the upcoming White House Down.
And now, thanks to a couple of recently released trailers, we have another recurring motif: holes being ripped in the sides of airplanes (or starships), and passengers flying out those holes to their (presumed) deaths.
