"A couple facing marital problems after losing their child finds their life together further complicated by a mysterious visitor."
Very slow and filmed using a handheld camera by someone obviously afflicted with Parkinson's disease, "Static" is a predictable hybrid of "The Strangers" (2008) and "Voices" (1973).
Apart from Sarah Shahi being absolutely gorgeous, that's all you really need to know unless you want the twist spoiled. The clue is in the gas masks not actually being gas masks, but if you look closely at the DVD artwork, you'll probably realise that for yourself.
As you would expect from a cast including Milo Ventimiglia, Sarah Shahi, Sarah Paxton, and a cameo from William Mapother (aka Ethan from "Lost"), the acting is okay. It's TV movie quality acting, of course, but there's nothing wrong with that. It's competent enough for what it is. It's just a pity that the ending is so unoriginal, and there aren't any scares.
Worth a rental, I suppose.
