You would think that HK films would have outgrown their terribly racist and sexist components as they have become more commercially successful in the global market - certainly their production values have kept up. But it must be the same tired hacks that write and produce this stuff as ever. Try not to notice the wildly sexist key plot elements as the male ad exec lead uses feigned romantic interest to seduce the half-Japanese female lead into his competition. It's not just a plot device, its the main plot element. Laugh along as he zanily tries to keep his real girlfriend from realizing that he has lured the woman under false pretenses - ha ha! Then, do your best to totally ignore the culturalist and racist component to the lead martial artist in the fray, the Towering Black Man. Blink and you will miss the homophobic poke during the creepy Hollywood-producer-as-sex-offender scene.
All in all, it's what you would expect from HK these days, or any days - wildly inconsistent poor-to-good action, combined with wooden acting and stale plot. Still, it was nice to see Yasuaki Kurata in his all-too-brief scene (cameo really) right at the beginning of the picture. He really is an amazing martial artist and even the little bit that we see there is a treat for the eyes. Go rent Fist of Legend and look for the girlfriend's dad if you want to see plenty more of him. In fact, do that and skip Anna in Bad Taste Land entirely. There are lots more and better romantic action comedies out there - do some work and find one for yourself, you will be happier.
Also, the bizarre misogynist girlfriend-shooting-the-female-interloper fantasy sequence was really awful - ugly to watch and unnecessary. The more I think about it, the more I realize there is a lot to dislike in this film.
To be avoided despite its alluring title and premise.
