(1) since it is on amazon, maybe it is considered an international release, hee hee 
click

(2) in case you think i highly recommend the film, read again ... hee hee ... i was cautious with my phrasing (becos i like to be encouraging and nice to directors/films) ... if i really like the film a lot, i would say HIGHLY RECOMMEND ... ha ha ... since you want my very frank opinion, i would say ... i was kind of "upset" that NOT enuf was mentioned/informed abt the person/backgrd etc ... in other words, if you go watching with zero knowledge about the history and hope to be very enlightened abt the person/events after watching, you would be disappointed ... however, if you want to know abt "life" in general during that period, maybe you will gain something out of it ... 

(3) black market ... in local context, it usually refers to the fact that since it cannot be shown commercially, people simply try to get the "pirated/illegal" dvds to watch ... like any other countries, the locals would usually know where to get the "prirated/illegal" dvds ... governments would usually try to catch them, but just like any other countries, you can never totally eradicate crimes/piracy etc ... i think same with china ... in the past, a lot of films may be banned, yet the Chinese have their means and ways to watch those films ... 

(4) local reaction to the film?! very frankly and humbly, i doubt many have watched ... i would say only the die hard art film goers might have watched ... i think opinions differ ...
