Wall-E

Personally I found Wall-E to be a very endearing character because of number of traits and qualities created by the film makers such as his inquistitive nature, for example when he goes out to work every day and finds the most random objects that a normal human being would have no care for, but to Wall-E the objects either baffle or amuse him. Such as an object as simple as a ring box. This leads me on to another point, the irony when he finds the ring box and throws the (what we assume to be very valuable (to us)) ring away and keeps this box, this emphasises his naivety which when mixed with his other childish and anthropomorphic traits, such as carrying a lunch box with him out every morning on his back like a primary school child makes him even more endearing.
Normally, a film with little or no dialogue in would put me off but I think that the characterisation of Wall-E and the setting and tone of the film, along with a nice uplifting happy ending made me made it a very enjoyable film to watch. It also made a nice change for a post-apocalyptic film, rather than the usual '2012' or '28 Day's later' style mass death productions.
