“Room For Rent” (**1/2 out of four) was an uneven melodrama about a lonely widow (Lin Shaye), beset by financial problems after her husband’s death, who rents out her room to a young man (Oliver Rayon) and develops an unhealthy obsession with him especially after him and another houseguest (Valeska Miller) fall in love. Shaye’s excellent and heartbreaking performance makes this worthwhile but once she breaks from reality and becomes erratic the movie does too. Film also doesn’t so much end as stop.
