Fun, but cheesy
1 March 2004 | by zengbo1234See all my reviews

The first time I saw Twins Effect, I was stunned. I bought it because the case (lovingly Pirated in China) was a picture of Jackie Chan and one of my favorite pop duos Twins. I thought I had to see it. I didn't know whether to love it or hate it. The character development is slow, but quite interesting. You really have to love the personality that each of the girls brings in.

Gypsy (Ah-Jiao) Really makes her mark as a possible action or drama hero. Her acting is very skillful, and thankfully not over-done. Helen (Ah-Sa) also brings charm to the screen but more in a quite concious over-acting (Which though sometimes annoying, is also quite endearing).

The Vampires are scary, funny and different at the same time. The film pulls elements from Buffy the Vampire slayer, as well as kind of a euro-coolness for the Vamps. It is a crazy mix and doesn't exactly pull me into the film, but it pushes the plot through and, though not convincing, they are fun.

Obviously some of the draw to the movie is the great ensemble cast which includes several Hong Kong stars and starlets. Jackie Chan and Karen Mok bring some of the funniest and most endearing scenes in the movie. Karen, as a booze-loving bride steals the scene in her short cameo.

Action, Romance, Vampires, and cool stunts really make this a good all around movie. It can be a date movie, or an action flick, or just a fun mindless movie. In the beginning I said that when I saw it I didn't know whether to love it or hate it. Well, now I've seen it about 12 times and I love it more with each viewing. My recommendation is give it a chance, you may like it.

BY the way the opening song done by Jackie and Twins is really cool, if you want to hear it with the vocals look it up: The song's name is "Bian Bian Bian" It really is a good piece of HK Pop.

I give this movie an 8 out of 10
