Another Heaven - 2000 - 6/10
AKA - Anazahevun // アナザヘヴン

Police arrive at a grisly murder scene.
Top of the victim’s skull is removed, gray matter simmers on the stove.
Other slayings follow, all reek of sexual congress.
The plot roars out of the gate with mounting horrors and kinky characters.
Alas, at the mid point of this Japanese cop show, the director eases off the accelerator.
The momentum never returns, the hectic energy dissipates.
The first half reminds me of a HK Cat III film, the second half methodically resolves.
