"Serial Experiments Lain" was first broadcast in Tokyo at 1:15 a.m. JST. The word "weird" appears almost systematically in English language reviews of the series, or the alternatives "bizarre", and "atypical", due mostly to the freedoms taken with the animation and its unusual science fiction themes, and due to its philosophical and psychological context. Critics responded positively to these thematic and stylistic characteristics, and it was awarded an Excellence Prize by the 1998 Japan Media Arts Festival for "its willingness to question the meaning of contemporary life" and the "extraordinarily philosophical and deep questions" it asks.
