Short films are tough. Most viewers have far less experience watching short films than feature length ones, and so are less fluent in the language of the genre they're viewing. Additionally, most directors have a harder time creating the "magic of the movies" when given only a fraction of the time - and often times a fraction of the money - they would have when working on a feature length film. Yet the challenges of short films, both for viewers and creators, can sometimes lead to truly wonderful films, and such is the case with Bradley Hawkin's Roller Coaster. It is an excellent film that manages to balance the timing, whit, and relatable characters needed to make a great short. As the lead, Sarah Hawkins demonstrates her versatility as an actress by managing to make you laugh all while being knocked around by a worst-day-of-the- year type situation. I highly recommend this movie to both new comers and seasoned veterans of the short film genre.
