Review: This movie kept me constantly entertained. In comparing this to Serial Mom, Mr. Waters has gone back to his grittier side. This is not nearly as polished.There is a dark side here. A message about how success and fame changes a person -- but more importantly how it changes the people around you.There is not a false moment in this film.The characters are somewhat cartoonish... but I want to believe that is what Mr. Waters is trying to achieve.It is fascinating to watch how Mr. Waters has evolved... This is truly his finest work. Question: is it a negative review?
no

Review: Director Paul Verhoeven's American vehicles are of varied quality, but most of the films he made in his native country are indisputable masterworks. This is the story of alcoholic (and bi-sexual) writer who moves in with a beautiful rich and very strange woman. But the lady does not know that he is only interested in meeting the woman's handsome male lover. In the meantime, the writer is plagued with strange visions - at first they look like hallucinations triggered by alcohol abuse, but he soon begins to realize that he is actually experiencing some kind of premonitions. Fascinating Hitchcockian thriller, very original and provocative. I love films that make you think they are about something, but then you realize they are about something completely different. This is one of those movies; a thriller during the first half, and a quasi-religious surrealist saga during the second half. Very erotic, original and blasphemous, not for kids or people that go to church every Sunday. Great cinematography by future director Jan de Bont. Highly Reommended!

Review: i liked this film a lot. it's dark, it's not a bullet-dodging, car-chasing numb your brain action movie. a lot of the characters backgrounds and motivations are kinda vague, leaving the viewer to come to their own conclusions. it's nice to see a movie where the director allows the viewer to make up their own minds.in the end, motivated by love or vengeance, or a desire to repent - he does what he feels is "right". 'will god ever forgive us for what we've done?' - it's not a question mortal men can answer - so he does what he feels he has to do, what he's good at, what he's been trained to do.denzel washington is a great actor - i honestly can't think of one bad movie he's done - and he's got a great supporting cast. i would thoroughly recommend this movie to anyone.
