Micheal Douglas has always been, at least for me, one of the better actors to portray a cop on screen. Very believable, very real, he just has a natural feel for this type of role. I think its due to the fact he starred as one on TV in "The Streets of San Francisco". Everything blends in this cop thriller. It oozes style and panache. It also has an underlying emotional core that I think gets underrated by critics. Douglas as Nick Conklin has some fine moments playing off the characters played by Andy Garcia, Kate Capshaw and especially Ken Takakura. This movie combines excellent acting, gorgeous cinematography, great atmosphere, along with some solid action set pieces...and gets it right. Director Ridley Scott brings all his cinematic guns to bear and spins these elements into a definitive police action thriller. I loved this flick when I saw it in 1989 and I still do. It may not be as audacious as when it premiered, time has seen to that(ex.action scenes have really gone virtual reality)but it's still a respectable addition to your DVD library. And of that fact there is no gray area!
