For a very young audience

Rating: 4/10 (8 July 2012)

Captain over the radio as the storm approaches: "Come back to the trailer kids, there is a huge storm approaching!" Reply: "But dad, we do not want to, we are having so much fun!" Captain: "No really, you have to come back. The storm looks dangerous, and besides, the journey here took rather long, we won't be leaving soon so you can go back there tomorrow and explore." "Dad, it's so cool here. And the storm cannot be that dangerous. A 300 feet high cloud of dust and debris in an unbreathable atmosphere, come on, there is nothing to worry!".
10 Minutes of visually stunning CGI and stop motion later, Captain: "See kids, I told you so. I should put you all over my knee for a good spanking, but I love you so much, that I am just happy that you are home."
In other words, the visuals are stunning, the logic behind some parts of the film can be explained (albeit in some areas awkwardly), but the characters action and motivations must have been written by a 13 year old. I think I would have enjoyed the movie when I was much younger, but I simply cannot take it seriously nowadays.
