Plot David (Ruffalo) gets more than he bargained for when he rents a swish San Francisco apartment — it comes complete with a ghost only he can see, former tenant Elizabeth (Witherspoon). She’s not about to leave, either, as Elizabeth’s convinced she’s not actually dead yet, so she enlists a reluctant David’s help to find out what happened to her.Verdict A sweet but predictable chick flick, this coasts by on the considerable charm of its two leads.
