There are many improbable plot twists in French police thriller 'The Promise', but that's just par for the course. Even before things get silly, however, the basic conceit lost me, due to its essential laziness: a policewoman starts digging into crimes her father, also a cop, had previously investigated; and because she cares, she is also right (or at least, more right than anyone else) about everything and thus justified in doing absolutely nothing by the book. There's a good reason we expect our real detectives to be dispassionate, but the opposite state of affairs is so common in television series it's not only inaccurate, but cliched. For me, 'The Promise' never rises about its hackneyed premise.
