Joseph Gordon-Levitt isn't playing an uninvited guest so much as a manifestation of chaotic grief in "Hesher," told from the point of view of a 13-year-old boy (Devin Brochu) whose struggle to overcome the sudden death of his mother is upended by the imposed arrival of the titular character.
Gordon-Levitt's long-haired, chain-smoking, often-shirtless metal-head squatter and his prankishly, profanely violent antics initially go unremarked on by young TJ's catatonic father (Rainn Wilson) and lonely grandmother (Piper Laurie). But they eventually serve as a wake-up call to the whole household that any kind of action is more emotionally healing than inaction.
