asian film subtitles

[tonto1]

recently I purchased The Detective 2 twice from hong kong via e-bay and had to send both copies back for bad subtitling. as world cinema is still a niche market in the uk surely there must someway of stopping this happening because i think this would put newcomers to this market off buying asian films.this has now made me very wary of buying from abroad and would still like to get the above film which is not available in england
