 By his own admission, the efforts invested in production of the two documentaries did not bring him anything more than financial damage and troubles, due to limited scale of theatrical screening and refusal of TV broadcasting corporations to licence the films (Mori refused to allow isolated scenes to be used in video sets to Aum-related news broadcasts).However, in 2010 he wrote a critically acclaimed book on the intervening decade of Aum entitled "A3".While his documentaries on Aum Shinrikyo were very controversial when they were being filmed and shown, Mori is today considered amongst Japan's most talented independent non-fiction filmmakers.
