I found this movie to be very entertaining with lots of wonderful surprises. There were lots of unexpected and entertaining moments in this film. This film deals very well with themes of friendship, mystery and love. The ending was very touching and unexpected. Though the action may not be as good as some of the Jacky Chan movies, this movie has a great storyline. The cinematography of the film was well made. The acting was extremely fantastic, especially the acting of Karena Lam. This movie has wonderful mystery elements as well. This movie even contains some horror elements in it though it was supposed to be a physcological thriller, there were some jumpy scenes. However, there are still some minor flaws in this film. I thought the middle portion of this film where the relationship of the two girls were being bulid up was quite draggy. It would be good if they have shorten that up a bit. This movie contains a lot of action, and well paced overall. This movie is a rather original one because it deals with kidneys. This movie is highly recommended. What I actually like most about this movie is the ending. The ending was very well done due to the built up of the film. The ending was though, predictable, a very touching ending indeed. The ending for this movie is very satisfying for me unlike the one in diary. The ending shows a great relationship between the main characters. A lot of credit was given to the ending for me. Hence, I will give this movie a high score of 9/10.

The urban myth in this modern Honk Kong thriller simply makes my skin crawl, and the film effectively pulls you along for an unnervingly captivating ride. However this dark concept is only a stepping tool for the premise to move along, then to focus upon it. Susan Chan's well-oiled story keeps the tempo tight, is held together by a strongly stimulating script and constantly stays busy with its cat-and-mouse layout. These do make up for the predictability of the film's material, and a silly surprise towards the end. Like the other user-comments have mentioned, the many twists that the framework throws up are pretty much foreseeable and some quite questionable, but director Chi-Leung Law still manages to competently construct slabs of unbearable psychological tension and grisly violence that teases the viewer. His direction might be economically executed, but he crafts out a stylishly bold and at times visual feast of perfect timing within his suffocating set-pieces. Going a long way to cementing a creepy atmosphere of despair, and uncertainty is that of a beautifully layered music score, which always packed a sudden sting and the sublime staging of Chi Ying Chan's crisp, moody cinematography. What really is the key of the success are the magnificently flawless lead performances of Angelica Lee and especially Karena Lam. Both bring humane, provocative turns that are truly convincing, and moving in every detail and the hazy relationship between the two characters is truly a complicated web. A very well made and professionally acted film, where from the get-go its faults seem immensely minor to disrupt a very entertaining, worthwhile story.

KOMA (dir. Chi-Leung Law -- 2005) starts off with a classic urban legend of a person waking up in a ice filled bath tub with an organ surgically removed. As the movie progresses, however, the audience is lead into a carefully crafted suspense thriller, reminiscent of Hitchcock and De Palma.The protagonist is a wealthy woman, Chi Ching (Angelica Lee - The Eye), who is suffering from renal failure, and is waiting for a kidney donation. Unfortunately, Ching has a rare blood type making a match difficult. She eventually befriends a woman, Suen Ling (Kar Yan "Karena" Lam - Heroic Duo), who is jealous of Ching's wealth and love life, and has several dark secrets, none of which I will give away at this time. All this is happening while a serial killer is going around stealing kidneys from woman. KOMA has one twist after another without falling into the cliché of coincidence. Every twist in the movie occurs because of the choices each character makes rather than due to outside forces, culminating in a great twist ending.Although shot in a style that is very reminiscent of DePalma, the themes are very "Asian", especially the friendship that builds between Ching and Ling. I don't really understand the "We'll-be- friends/sisters-forever" type themes rampant in Asian films centered around Asian woman. Seems childish to me. Perhaps something is lost in the translation. Perhaps it's because I'm just a guy. Maybe both? The screenwriter is a woman by the way: Susan Chan. She also wrote the script for Jackie Chan's Who Am I?The other downside of the film is that I don't know why it's called KOMA.It is, however, refreshing to see a suspense film come out of Asia that doesn't revolve around killer Harajuku girls, or ghosts coming out of a television set. It's fairly impressive for an Asian suspense film. The films is rated "R" for brief nudity, violence and gore (blood).Great suspense, story and cinematography, but very poor on dialog.

SpoilersTwo years ago, Karena Lam Kar-Yan and Angelica Lee Sin-je established themselves as credible thriller actresses in Inner Senses (Yee Do Hung Gaan) and The Eye (Jian Gui) respectively. The former is a psychological thriller, and the latter a ghost story. Their talents are not limited to thrillers, as they have convincingly demonstrated in their many other works, particularly in the case of Lam. It is interesting though to see them brought together, in another thriller.Koma is not a ghost story, and not even a psychological yarn to the extent that Inner Senses is. It is a variation of the familiar rich girl/poor girl tale set in the traditional mystery thriller genre. Lam is the poor girl, bitter, manipulating, reckless. Lee is the rich girl, whose good fortune is marred by health problems. The story revolves around these two girls, the relationship that develops between them, and the eternal triangle they are entangled in.While the plot is far from being flawless and generally predictable, it's reasonably coherent. The script is decent, well paced between story telling and tension building. A strange thought I had however is on a message that I'm sure is absolutely unintentional: don't report a crime to a police but instead be a beneficiary, and you'll probably live happily ever after.The highlight of the movie has to be the two young ladies, who take this movie a notch above what it would have otherwise been. In a radio interview, they talked about how they, knowing each other only by fame but not in person before, had to quickly develop a rapport during the filming of this tension-filled movie. These two are unquestionably the best Cantonese speaking (they're actually even better in Mandarin) actresses among their peers. To watch their acting individually is a treat. To watch them act together, one truly appreciates the synergy.One last thought. In recent years, Hollywood seems to like buying Asian scripts for adaptation. The Ring is the best example, an adaptation from box office smashing Japanese horror Ringu. I believe they have also bought Korea's My Sassy Girl and Hong Kong's Infernal Affair. Would they consider this one? If they do, casting will be interesting. I would venture to suggest Christina Ricci and Alison Lohman, for Lee's and Lam's roles respectively.
