LOVE this movie... got a copy of it a few years ago and did some research.. it was a surprisingly involved mythology, and supposed to play out over a trilogy set in what might or might not have been the afterlife. The question of what world it was set in was one of the main things actually..
Unfortunately the critics who raved when it debuted later turned around and said they hated it, elsewise we could have had 2 more of these..
oh and btw.. and unofficial sequel with Michael Pare was done a few years back, but word on the street is that it should be avoided if at all possible..
I expect your review shortly.
