This introduces a new, weaker plot with the same type of gore, moving from new-gothic blue and watery-green (Matrix, Saw, Ring) to now in new 30's artistic slant print yellowish neo-gothic (more concentrated than Sky Captain). It said to me, "soon to be a PS2 /3 XBOX, GC, PC game".
Though not totally predictible, it was, inevitably, somewhat predictable.
Two victims (supposedly bad or evil in their own right) weren't really investigated, and you never knew much about them. They were, I guess, slasher movie fodder. The shared theme they had were vices, so a character in the movie was a vice officer, which seemed strange considering his "role" in the main investigation
Vice: narcotics, prostituion, I guess larceny falls under that category, but certainly not homicide.
Anyway ... watch it if you saw the first one, but this is hacked together --- I won't give any numbers on it
