It was all downhill for Kevin McCallister...

Macaulay Culkin guest starred on the first episode of :DRYVRS, a web series by Jack Dishel, where the 35-year revisited his most iconic role -- the clever child at the center of Home Alone. Somehow, amid all the nostalgia, we never stopped to ponder how dark the movie really is, which is why it's so jarring to find a jittery adult Kevin, still plagued with abandonment issues and haunted by that fateful Christmas when his family literally left him behind to deal with two deranged burglars.

Fair warning, the video is NSFW, contains explicit profanity, and allusions to violence that is much more disturbing when carried out by an adult than when it was perpetrated by an adorable 8-year-old.
