Man, that Det. McClane ought to be given The Ultimate Survivor award.
He managed to live through being shot at by multiple automatic weapons from multiple bad guys, shot at by a fighter jet, falling off aforementioned fighter jet onto semi-destroyed freeway slanted at an 80 degree angle then sliding into concrete debris, thrown out of a speeding cop car, blown up by a rigged computer, blown up by natural gas in a power plant, falling from a height equivalent to oh, about 3 flights of stairs.
Hmm...have I left anything out? I probably have.
Despite Det McClane's apparent immortality, I did enjoy the movie. It was mindless entertainment, with amusing dialogue, and fantabulous stunt work (although these days with the extremely high quality of CGI, it is sometimes hard to differentiate between what is virtual & what is real).
