Writer-director Anna Zlokovic doesn't waste any time establishing the horror premise of her film Appendage. Immediately in the first scene, it's clear that there's something very wrong with aspiring fashion designer Hannah (Hadley Robinson), and things only get worse from there. So many modern horror movies rely on slow builds and vague hints that it's refreshing for Appendage to reveal its grotesque monster early on. The problem is that Zlokovic runs through so much plot so quickly that Appendage nearly exhausts its premise before it really gets going. The one-note allegory about a monstrous manifestation of the protagonist's anxieties and fears wears thin before Appendage is halfway over.
