I've seen Brighter Summer Day and Yi-Yi from Yang. I got Class Relations from a DVD-r which looked like a transfer of a 16mm print. The quality was terrible, but with a film that rare, I'll take it anyway I can. The same guy had two more films from them which were probably in similar transfers, but since I was unfamiliar with them I opted to pass for now. I wish there would just be a full retro, I still don't even think New Yorker released Moses and Aaron which has been coming soon for the last year. I know New Yorker owns most of the rights to their films (at least in the US) and the print I saw of Class Relations had the New Yorker Films Release logo at the beginning. I'm curious to read Kafka's Amerika because from what I'm told it is a very literal adaptation, including the unfinished ending.
