A surprise back-from-the-brink redemption proves reliably engaging in rock-doc “Last Days Here,” tracking three years in the life of cult musician Bobby Liebling, whose band Pentagram never capitalized on its early promise. First seen as a tragic casualty, strung out on heroin and crack, living on the charity of his elderly parents, the singer is dragged toward a hopeful future through the intervention of a fan-turned-manager and, more remarkably, the love of a good woman. Pic is probably a tad too generic to reach far beyond its core aud of 1970s heavy rock fans.
Don Argott (“Rock School”), here teaming up with Demian Fenton, has found a subject who’s most remarkable for still being alive. Accurately described as akin to a frozen caveman with active DNA, Liebling also harms himself due to his paranoid delusion of parasitic infection. This freakshow might have soon worn out its welcome were it not for the engaging presence of parents Diane and Joe Liebling (the latter a former security policy advisor who worked for eight Secretaries of Defense) and especially of indefatigable manager Sean “Pellet” Pelletier, whose belief in Bobby is ultimately rewarded.
