YMMV / The Twins Effect

• Cliché Storm: The film uses a whole bunch of cliches about fighting vampires from asian pop culture, including a cool european main villain and a vampire hunter who himself turns into a vampire. However, this is not annoying, because the film does not try to take itself too seriously.
• Complete Monster: Duke Dekotes leads the rebellion against the royal family in his quest to become even more powerful with the blood of the Ultimate Vampire. Starting his reign of terror by committing a series of killings, Dekotes assassinated five of the princes—one of whom was only a little boy—and collected their blood essences in only two months, before going to Asia in search of the last surviving prince, Kazaf. Releasing his vampires to wreak havoc around the city, Dekotes kills the partner of vampire hunter Reeves after his followers massacre countless humans on a train. When Reeves finds him again, Dekotes defeats him and allows him to turn into a vampire, forcing his sister and pupil, Helen and Gypsy respectively, to kill him. Executing Kazaf's loyal guardian, Prada, Dekotes opens the book that contained the blood of the Ultimate Vampire, admiring it instead of helping his followers.
• Incest Subtext: More by accidentally than implied intentionally, but what do you want from the movie where the sister fights with the brother's girlfriend for his attention?
• One-Scene Wonder: Jackie Chan's fight with biker-vampires in the middle of the movie. Actually, this was implied initially, because it is a cameo of one of the most popular Chinese actors at the moment.
• Les Yay: It seems that the main heroines are too close to each other, especially against the background of the fact that all the men in the film are either villains or outspoken side characters. In the end, they even make up a "couple" of tsundere/nice girl.
• Narm Charm: Vampires. Oh, boy. It seems that the whole film actors more depict people who want to pretend to be vampires for a joke than real monster characters.
• Misaimed Marketing: In most countries outside of China, this film was distributed as a Jackie Chan film, despite the fact that he appears only in one scene.
