《一号收银台的女孩》的剧情让观众有代入感，节奏令人舒畅，氛围浓厚，制作让人震撼，该片“跳出”了血缘链接的原生家庭来观察家庭对人成长的重要性。“不以血缘定家人”，正是这部剧的基调，它打破了传统意义的“家人观念”，重新定义了“家人”和“家庭”。

影评:

1,导演用煽情朦胧的画面，唯美的音乐，出乎意料的字句，勾勒出一部让人期待的美好而又动人的爱情故事。

2,这部影片拍得聪明又灵活，满足所有超级英雄电影具备的元素。

3,该片无疑是一部超高水准的作品，从始至终。

4,美丽的女人骤然出现在面前，总是引人注目，泫然而逝，但是我们从未真正看透她。我们只见到躯壳，我们被美丽的外表蒙蔽了。爱上一个漂亮女人比什么都危险。我对你一见钟情……但直到今天我才允许自己真正去体会，我一直先做考虑，毫无畏惧地下决定。今天因为你，我从你身上学到……我做的每个选择都不同了，我的人生已经彻底地改变了。我学到了如果自己那样做，才会过着充实的生活。不管剩五分钟或五十年都无所谓。

5,我很久前就意识到，你是在车站和地铁会跑起来赶那趟车的人，而我则永远保持一个节奏，宁可错过眼前的也不愿变更自己的步伐。但是我始终没有与你提起这一差别。因为我发现，在即将错过你的时候，我也曾跑了起来。
