Positive reviews for this film are forgiving and I think based mostly on concepts only pointed at by the film, not actually realized. Yes, the premise is great, but the impetus of the movie shifts and the acting is spotty at best. I don't mind having to figure things out as I go--that can be the appeal of a film--but the cast and crew seemed to also be developing their vision as they filmed. Most important is that the co-star's character is sorely underdeveloped given the crusader she emerges as in the end. They recall bits of the movie that were to have foreshadowed this, but the effect flops. Somewhat similarly, the main character's motive for using Z has to be stated explicitly at the end. While it makes total sense with the movie content, he's too much of a mystery otherwise to triangulate/confirm. What's less of an issue, but still sticks out is the poor acting of the inexplicable villain and the absurdly, grotesquely incompetent acting of the detective. It's probably not all the fault of the actor, though, as no one seemed to have a clue what was or was not supposed to be driving the film, which also contributed to the empty acting and tedium.
