Apparently our planet is a delicious place, or at least we can assume so from watching Disneynature’s newest documentary, “Oceans,” a 103-minute tribute to maritime critters eating the hell out of one another.

The Disney subsidiary’s second Earth Day release (following 2009’s “Earth”), this year’s watery documentary might suggest that nature is inherently gluttonous, and audiences may likely align themselves with the film’s array of predators, rejecting their stale theater popcorn after laying eyes upon footage of succulent crabs and tantalizing sea lion calves.

Aquatic buffets aside, though, “Oceans” actually proves to be a relaxing and delightful enough experience to warrant a recommendation. With four years’ worth of footage from each of Earth’s oceans, the film portrays as much mystery and wonder as it does feasting.

Of the film’s wildlife, there are the expected players, such as great white sharks and a variety of whale species, but “Oceans” also includes plenty of unusual fauna that are sure to titillate even the most hardened of audience members.

If the prospect of going out to watch a documentary is not particularly exciting to all viewers, “Oceans” will show their doubts to be unfounded as it confirms that all of life is a compelling (and oftentimes humorous) narrative.

Of the film’s more comical sequences is one found in the “oceans at night” segment, in which a seemingly paranoid mantis shrimp, diligently protecting its home, engages a passing crab in as intense a battle as any that can be fought between two crustaceans.

Despite its many merits, “Oceans” becomes as equally polluted as does its subject matter in a number of segments, due mostly to a certain degree of heavy-handedness on the part of the filmmakers.

While the first half of the film effectively draws in viewers with intriguing creatures and a perpetually alluring aesthetic, the latter half may equally repel them with commentary on global warming, pollution, and over-fishing that seems to have no purpose other than to cast guilt upon audience members.

These flaws aside, the film’s most unforgivable sin comes with the closing credits — a “special track” recorded by Demi Lovato and Joe Jonas. In direct contrast with the film’s rather powerful score, the Lovato-Jonas “Make a Wave” may very well send audiences home with a nasty cheese infection.

All issues aside, “Oceans” remains a worthwhile watch (the narration by Pierce Brosnan alone proves particularly poetic), albeit one that will likely lose much of its power and visual charm once it leaves the big screen for home release.
