I must warn you that The Assassin is a very artistic film so it is not recommended for all viewers. I brought my mom with me to watch it and she didn't like it at all. For her, I think she had the preconception that it would be something closer to a commercial film. For me, I think it's definitely a film that requires their audience to think after they watched it. I thought it was curious that director Hou Hsiao-Hsien picked such a strange aspect ratios for the film. Don't expect the film to be in 16:9 widescreen, guys, but don't worry, there's color.
