If “The Jungle Book” is like taking a trip to Disneyland, then “Mowgli” is a hike straight into unknown woods with nothing but some duct tape and a Bowie knife.

The abiding darkness and occasionally graphic visuals will likely reduce its appeal as talking-critter family fare — think growling nighttime campfire tale instead of sun-dappled spectacle — but it makes for a welcome swerve from the Mouse House’s fun-zone approach to these timeless stories.

The filmmakers are clearly trying to bring an uncommon maturity to the fantasy film, and in many respects they succeed. While not everything here works, what does is impressive.

It’s intellectually intriguing and well-acted, but the inconsistent visual effects undermine the necessary suspension of disbelief when it comes to mixing live-action humans with talking CG animals in such a serious and somber adaptation of the Kipling classic. Still, it’s a thoughtful and dramatic interpretation, which sets it apart from most incarnations of The Jungle Book.

While the film’s perception of the politics of the jungle is often profound, the same cannot be said of its take on the human world.
