What a waste of resources and potential... I have lots of respect for Michael Arias for his work in Tekkonkinkreet, and Nakamura has been partaking in the making of great films as early as the 80's... The problem is not the direction, it's the scenario. World-building is quite fine: a utopian & futuristic environment living under the ideology of "lifeism" where people are connected through a centralized system that values safety, self-preservation and empathy above everything else. So far so good... but after the exposition segment, the events start taking a curve that bends away from any reasonable or believable development. The writing is ridiculously bad, the ending both lazy & lousy.水准之上的悬疑类型片，反转合理、节奏鲜明、bug不明显，失忆、催眠、现场再造的元素运用得当，历史背景的切入也提高了几分真实感，主观镜头的运用极具悬疑气氛，虽然这种一失足成千古恨的“浮士德式交易”剧情点套路比较多，最后落脚点和人物关系都有些刻意的痕迹，但是并不是什么大毛病，欣赏这样的电影，完全不要看剧情介绍还是很重要的.     角色（jué sè 旧又可念jiǎo sè）是一个汉语词汇.     又作“脚色”（jué sè 旧又可念jiǎo sè）.     词义是指演员所扮演的剧中人物（有主角，配角之分），后来又引申指比喻社会生活中某一类型的人物.     【参考资料：】.
