Theo Robertson One of the problems of having a film with a single protagonist is having him or her communicate with the audience . You can achieve this via voice over that quickly outstays its welcome , or possibly you could someone writing in a diary but who wants to watch film with the lead character constantly put entries in to a journal ? It's easy in literature when you can spend page after page having exposition and thought process in prose . It's near impossible to translate this to screen which explains why there has never been a satisfactory adaptation of Richard Matheson's I AM LEGEND Greek film maker Thanos short film REMNANT suffers from this . Looking on the bright side if a film is Greek and no one speaks then it's very easy to market for an international audience , after all silence is an universal language but it can also make for an uninvolving story . That said the running length is appropriate for this type of short and the end scene is far more downbeat than I would have expected
