Yippee Ki Yay, all over again!
They changed the director trying to continue with the plot of the heroic McClane but this time it didn't work for them.
Everything said above is reflected in a regular script, without much ingenuity, the same story as before but moving to an Airport with terrorists as villains again.
A regular sequel that is not even up to the first. This movie is only necessary if you want to continue with the other movies in the saga.
