I really really enjoyed this film. Grated it was very very very long but they kept you busy with interesting scenes all the time. From learning the ways of the creatures in the water, to the lives of Jake's children, this film kept you busy and distracted from the fact that it was 3hrs long, for the most part. The action and the beautiful scenes of gliding through the ocean with mesmerising creatures makes the an incredible film to see in 3D, in cinemas.
