First of all , the narration ruins everything. From the first scene . The film then seems to be a documentary . Not anything else . Maybe it was intended so but still they could have found a better voice too. More cinematic . Too bad for the money . The lead Ao is great as performance but Aki is a bit ''too much '' in her performance. The director seems to not see this .
Two . For this kind of money they could get much better cinematography . Which is a big part of any movie . (See Alpha 2018 ) . The story is interesting and brilliant at times though .
Three. Music ,again , for this money is bad too . Sound seems to be good enough though.
Anyway ,it shows why the movie didn't make money . And it feels too unreal at times too. I guess the director wanted a lot of accuracy of the era but then again we can't know exactly how they lived back then . We never will .
Worth watching anyway . Cheers!
