One thing that Michael Mann is great at doing is leaving the viewer feeling overwhelmed. He does it again with this epic action/thriller. The scope of this film is enormous and the performances are phenomenal especially from De Niro and Pacino. Other than that is there a reason to see this film the answer to that question is a most definite yes!! I was enthralled by every frame and shot of this picture as I was watching it I couldn't help but love all of the characters (even the villains) there is so much story and character development that the action almost gets in the way. All in all I think that this is one of the most beautiful and compelling thrillers I have ever seen and if you love film at all you should most certainly see it!!
