Director John McTiernan handles the action sequences perfectly in this action movie from the 80s. He not only does that well, but also develops the characters as the movie progresses.
The exceptional screenplay written by Jeb Stuart and Steven E. de Souza, about a cop who gets caught in the middle of some ruthless criminals taking everyone in an office building hostage, gives the director some good stuff to work with.
This was a great role fro Bruce Willis.
