In fresh dramedy "If You Were The Last" astronauts Anthony Mackie & Zoe Chao are stranded alone in space for three years on a charmingly lo-tech spaceship (which is in no way authentic - that's not the film's vibe) with no comms to earth but food, air and batches of music & movies. To pass time they ponder issues like the pro's & cons of sleeping with each other - including the emotions involved (or lack thereof). Geoff Stults & especially Natalie Morales give good support, and Kristian Mercado directs with fine quirky style on his debut, matching debut writer Angela Bourassa's script that's more light, bright, chick-flick than legitimate sci-fi. A good, effective, original film.
