When you make the decision to call your 3-D animated feature “Epic,” you obviously put some pressure on yourself. Alas, Blue Sky Studios, the outfit behind “Ice Age” and “Rio,” isn’t entirely up to the challenge. Their fantastical great-outdoors adventure is certainly very pretty to look at, and has a general agreeability about it. But the movie would need to engage us far more powerfully for that hyperbolic title to fit.
Director (and Blue Sky co-founder) Chris Wedge and a gaggle of writers take the seed of their story from “The Leaf Men and the Brave Good Bugs,” a picture book by William Joyce. But the film really doesn’t make use of the book’s visuals, gentleness, or anything beyond its rough concept.
