While the premise of Another Heaven sounds interesting enough (a police thriller with supernatural overtones), the film itself comes off a little uninspired. Iida spends too much time on a setup that doesn't deliver anything original, while skipping through the supernatural elements without too much conviction.
Detective Manabu finds a man with his brains removed in a little apartment. It's the start of a tricky cat and mouse game with a killer that seems to have superhuman capabilities. Manabu isn't discouraged though and what the help of his partner and a girl who has fallen in love with him, he slowly closes in on the killer.
The film takes too long to get going, the cinematography is a little basic and Eguchi makes a pretty boring lead. Luckily Miwako Ichikawa adds some spice to the film and the ending turns it up a notch, but it's not enough to turn a 130-minute police thriller into a riveting film.
