I know 3 kids that go friggen bonkers watching the movie because they love to enact the scenes in realtime. There is something new every 5 mins to keep them absolutely engaged.
Personally, I couldn't get past the mental block of being reminded of how much I utterly F'ing hate living where it is hot or anything to do with the desert. It depresses me, and seeing other people stuck in that environment depresses me.
...and there is one music track in there that only reminds me of when it was used in The Kingdom. So it just feels weird to relate to when it is used in Rango, even though it seems like a reasonable choice.
It is interesting to see how they play on a socio-political theme of "control", if you want to read into it to that degree.
. In this case, the object of control is water
All in all, a rich production that has many levels of enjoyment between children, adults, and intellectual pondering. I just couldn't get past my aversion to desert life to really submit to the content.
