One scene I hate in that movie is a scene wher Jamie Lee has an Uzi (or Tech-9, or some such), which she drops at the top of some stairs. As the gun rolls down the stairs, it fires repeatedly, which is completely unrealistic, and intended, IMHO to reinforce an irrational fear of guns.
That part makes me cringe everytime I see it. Even worse is that the Uzi hits several bad guys. Still a fun movie.
