A character study in search of a character, the badly overheated medical drama “The Good Doctor” stars a toned-down Orlando Bloom as Martin Blake, a young doctor from Britain starting an assignment at a hospital in West L.A. Martin quickly – and inexplicably – becomes obsessed with Diane Nixon, a barely-legal kidney patient (blank-faced Riley Keough), hurdling doctor-patient boundaries like Edwin Moses: he first accepts her family’s invitation to dinner, then switches out her meds so her condition worsens (she seems rather glad of it), then worse, much worse. (He also turns his apartment into a pharm lab to make Oxy to placate the orderly who gets hold of Diane’s diary.)
