this be a great film with a lot of strong philosophy weave in and i be not surprise to find that there be a great book behind this film . the central plot for the film be a 2d world and two faction within it . right from the start of the film you be bombard with parallel to reality and it hard not to get distract by your own thought chain and in a good way positive . the cgi be as good a it need to be to tell this story and the yellow sphere that you will have see if you have read this far be a bit mislead the film have it own unique style that extend further than such basic geometry and reflection . the actor voice over be quite good and the film isn not amateur and there be a lot of narration to help the story along . my main criticism of the film would be an excess of narration sometimes it useful but other time it downright patronising and by the end you end up sigh every time you see narration .
