13/13/13 is a typical indie horror film with a story supposedly based on Mayan prophecy and the like, although in fact it feels more like your bog-standard zombie flick. It's one of the very cheapest films that The Asylum have ever put their brand to, and that's saying something. There's little menace here, and some cheap gore, amid plenty of bad language and worse performances. The whole thing is infused with predictability and stupidity in equal measure. The worst thing about it? The cheap digital look which saps it of life and vitality, rendering it blue, grim, and depressing.
