I've been a fan of directing/screenwriting duo Adam Wingard and Simon Barrett since A Horrible Way to Die back in 2010. What's impressed me most is their movies tend to lean toward horror, but the tone and filmmaking style shifts from flick to flick to suite the story. So how do Winged and Barrett handle a (kinda) loving tribute to 80s action flicks? With some British guy who stars in a period drama called Downton Abbey in the lead? Stick with me! A soldier introduces himself to the Peterson family, claiming to be a friend of their son, who died in action. After the young man is welcomed into their home, a series of deaths seem to be connected to his presence.
