PROBLEM: Review: Shamefully, before I saw this film, I was unfamiliar with Helena Bonham Carter.I had to do some research, in order to assure myself she wasn't actually afflicted, as was her character, with (well?), what she was afflicted with. I was in absolute awe of this beautiful lady. She pulled it of flawlessly.Who would have thought that sexually explicit circumstances involving the final wants, and needs, of a unique young lady, could be interpreted as tender, and romantic? Well, they can be, when the right performers present them in the proper manner, as they did in this wonderful movie. I forgot to mention how dynamically beautiful Miss Carter looked in this movie. I have often said she was the most beautiful creature to have ever graced the face of our earth, but she seemed to have out done herself in this particular movie.I hope any of you who watch this movie enjoy it as much as I did. Thank you for letting me express my opinion. Question: is it a positive review?

SOLUTION: yes

PROBLEM: Review: At first,this movie seems so bad that i almost fell in a trance the first time i saw it.It was like a bad dream.A cosmic bore.But i gave it a second chance,then another and another,etc...I finally got addicted to this film,due to it's dreamlike slow pace,wonderful natural sets,bathed in a mellow autumn light and especially the musical score,which is made of some 70's progressive rock and absolute exquisite folk songs by actor/singer/songwriter Derek Lamb(the Troubadour).You should notice the song about hazel wood,silver trout and lady vanishing in the air...,heard in the middle and near the end of the film.There are some carnal scenes in the beginning ,wich allow us to appreciate the natural charms of Elizabeth Suzuki.If that movie had been made by some "repertoire" directors like Bergman,Lars Von Triers or Jean-Luc Goddard,critics would have rolled on the floor,raving about that movie as if it were a cosmic masterpiece.I personally think this film is one million times superior to any of Fellini's cinematic sh#@t!Definitely not for the pretentious. Question: is it a positive review?

SOLUTION: yes

PROBLEM: Review: One of the most nihilistic and brutal films I've ever seen, but also one of the most tragic and moving ones. This is an action-melodrama like the world has never seen it before. Sometimes the plot got me close to tears, while in the next moment delivering shocking revelations like a bone-crunching blow to the guts. Chilling performance by Edison Chen. The story of a HK-Cop and a Cambodian killer hunting each other down, while bit by bit losing their humanity, is a strong one. Featuring very little dialog in favor of haunting imagery and gritty camera-work, "Dog bite Dog" is pure HK-Bloodshed without the Heroism. Question: is it a negative review?

SOLUTION:
no
