这个是buffy（捉鬼者巴菲）的衍生电视连续剧作者兼导演Joss Whedon 觉得《buffy the vampire slayer》拍摄到第二季时收拾率不错就带上buffy的吸血鬼男友开了另一个剧组《angel》一派就拍了5季.
Just as Buffy was intended to capture a sense of the suburban oppression experienced by many teens, Angel depicted the feelings of loneliness, danger and callousness often attributed to the urban Los Angeles megalopolis. The divisions between the ordered world of the day and the chaotic world of the night have been trademark themes of noir and by depicting a protagonist who literally has no daytime life, the series was able to explore these same themes in more dramatic metaphorical ways.
