I don't ever give out ratings to short films, only features, but I'm making an exception for On Your Mark. How Miyazaki managed to make my heart heavy for three characters I knew for all but six minutes, none of whom speak, is a feat I don't think anyone has done before, for me, in a short. Using the lovely music as a backdrop was incredibly ingenious and added another layer to the emotion. This could easily be a feature, and that's my only issue with it, is there's a lot that happens, just wishing it was a tad longer to extend some of the events. It gets the job done. If you missed this, watch it now here, you won't regret experiencing it. You'll have the song stuck in your head.
