I have seen both IN CHINA THEY EAT DOGS and it's prequel, OLD MEN IN NEW CARS, and I have to say that this is the best of them. Where OLD MEN is a little more formulaic and recognizable as an average crime comedy, CHINA has fantastically bizarre elements that surprise and alarm. It's amazing how comical death can be if handled in the right way.
The film does bring up genuinely philosophical questions of right and wrong that, in my household, spurred interesting discussions about morality vs. social norm.
By the end of the film you most likely will be thinking about the same things and hoping that in your last hours you too will be able to avoid the men in the funny pants.
