If you ever imagined that a forest was inhabited by tiny leaf people, you were either dreaming, imbibing something other than water, or guilty of having way too much time on your hands. Blue Sky’s new animated 3-D film “Epic” is indeed about tiny leaf people and the human girl, voiced by Amanda Seyfried, who joins their righteous cause in the battle against other equally teeny arboreal denizens.
Director Chris Wedge falls into the common animator’s trap of making the “human” characters a lot duller than the nonhuman creepy-crawlies. Colin Farrell, Josh Hutcherson and Christoph Waltz join Seyfried in the voice-over corps, and their line readings are often more spirited than the visuals. Grade: C+ (Rated PG for mild action, some scary images and brief rude language.)
