This is a FRIEDKIN movie. Consequently, it is soulless, dark and physical. There are no heroes, the range goes from unclear/mixed up/tortured souls/loonies to the dephts of hell. It is also highly interpretative, you can not expect a logical script and a "I did it" smile or a "walk towards the sun" type of ending. So, it's a question of taste if you like his movies or not. I DO. I very much doubt that Pacino or Sorvino regret making this film. It is riveting. For one, characters are not even gray, they are a mystery. Sorvino's character, for instance is so blank, that you even wonder if he cares about anything, including Burns' fate. Pacino's character is pretty ambitious, but other than that he is completely controversial. Although he shows some kind of goodness (towards his neighbor, for instance), the ending even kinda questions that (was it because he had sexual intentions with the guy or that he just wanted to do some good?). Also, he sometimes feels overwhelmed by the undercover job ("I don't know if I can do this") but then he starts to adapt. One of the possible ideas of this movie is: you dance with the devil and then you start to like it. In any case, it leaves conclusions to the viewer. The atmosphere and especially the music are truly amazing and original. 9/10.
