total garbage ###SPOILERS###

Rating: 1/10 (29 April 2014)

DH(1) had quite some Hollywood stuff in it, you know, things that simply don't happen but... DH2 is not only overly full of it (McClane has more bullets in his handgun then the bandits in several submachine guns; the bandits can shoot at him for ½ an hr without even scratching him and he kills at least two with a single shot... the usual Hollywood crap, right?)
where it gets much more annoying is when it comes to the planes and air traffic...

holding patterns are not some sort of heap where passengers can wave to other planes - the planes are following each other.

crashing a plane by giving it a lower altitude of the airport / runway then what it really is; modern planes have a ground proximity warning system (GPWS for short) which... warn the pilots when the plane is getting too close to the ground, no matter what the tower tells there altitude is.

make yourself a favour, don't wast your time on this... 2 all the others are more realistic in their... craziness. except for the Hollywood standard stuff, of course...
