So it's not just big screen buffy/angel?
Its not magic stuff - and the point of that content was all metaphotial/allegorical/genre busting stuff anyway.
It has witty dialogue (gasp!). Its got that wry humour that Buffy and Angel had and good characters. One of the more respected film reviewers (this guy is NO Leonard Maltin) here said that he felt like he was watching Star Wars in 1977. I am biased 'tho, this particular reviewer is my favourite one.
