It's not often a film has the impact on me that Avatar did. It's not a brilliant film by any means with a script that was so-so. However the premise of this film is excellent and the messages in the film are thought provoking. Above all this film is extraordinary visually and if you only see it for the visual experience it's a must see.
I'm not about to spoil it by talking about it too much but this film but if you've ever read any of my 'Theory of Everything' posts, this film really speaks to that and our connection to everything around us. It is worth seeing and if you have a chance to see it on the big screen or better still in 3D then you really should do it.
