“The Shelter” (** out of four) was a murky melodrama about a homeless man (Michael Pare) who wanders into an abandoned old house and soon finds that he cannot leave and how ancient spirits in the house bring him back to his youth when he was a troubled husband and father. Or something like that. Pare is excellent and re-affirms his status as a solid character actor but he is defeated by a muddled and at times incoherent storyline and script. About on par with the recent “Cardboard Boxer” in which Thomas Haden Church played a homeless man struggling to stay alive.
