For me, White House Down is even less believable than Olympus Has Fallen. People in White House Down also make incredibly stupid decisions, such as why a terrorist would let a little girl live even after knowing that she posted the terrorists’ faces to the internet. The little girl’s final act, and its consequences, can only occur in a movie.
Even though White House Down is even less believable, it is the more entertaining movie, as shown by its higher worldwide box office. (It is higher but it is still a loss, while Olympus Has Fallen may make a profit due to its lower budget.) The entertaining factor comes in form of what happens to the helicopters and a passenger plane, the presence of jet fighters, who uses the rocket launcher, a car chase within the property, the little girl’s final act (yes, even if it’s totally unbelievable), and the surprise revelation of the ultimate villain.
