I'm not the world's biggest fans of scary movies. Mostly because I'm a huge scardy-cat; the last one I saw was Sinister and I spent most of the movie with my fingers lodged in my ears (I find that the soundtrack is usually the most terrifying bit) so it'd have to take something special for me to willingly sit through one. Alone. In this case, that something special was Doctor Who's Karen Gillan, who seems committed to making a mark across the pond (pun intended). I was totally prepared to ignore this film until my friend Nicole mentioned over brunch…
