This was another inspiring animation from Carlos Lascano, who also directed the charming "A Short Love Story in Stop Motion"."A Shadow of Blue" combines in a very clever way CGI animation with some live action elements (A shadow) resulting in a very captivating story about childhood's innocence and imagination.Without being entirely perfect, the result is more than watchable because of the good quality of the animation and the beautiful music. Perhaps it was a bit longer than it should have been, but the result was pretty satisfying anyway. Also the ending managed to be something sad and uplifting at the same time. Totally worth-watching.
