The Navi are a mix of live actors and cgi FX, and this has been shown to work very well on such films as LOTR and Dsitrict 9, but here it just looks terrible.The characters and dialogue are dull and unengaging, the action sequences standard running-away-from-big explosions fare, but as i say, it is the well-meaning but incredibly patronising plot that really had me gnashing my teeth throughout.
