This kind of story needs a heroine who's both charming enough to carry the action, and believable as someone whom no one expects to be good at detective work. Fortunately, McKenna-Bruce is slyly funny and cool in the lead role.

Agatha Christie’s Seven Dials is quintessentially cosy entertainment, but its broader function is providing a breakout role for Mia McKenna-Bruce, who’s quite brilliant in it.

McKenna-Bruce is delightful as the pint-sized self-proclaimed detective determined to do whatever is possible to find out what happened to her friend. A few of the clues unveiled in “Seven Dials” are more obvious than others, but there are just enough surprises to make the series worthwhile.

Netflix's adaptation of Agatha Christie's Seven Dials takes a passably entertaining murder mystery and tries to raise its emotional stakes with mixed results.

If you have neither read the original book nor care about the changes, this is a diverting three-parter. Christie purists may feel differently. The ending is completely new.

Across three tepid hours, Christie’s killer story is wasted on a series that feels dead on arrival.

The latest attempt to adapt the Queen of Crime’s work is a dismal failure: There’s no regard for Christie’s prose, no idea who the series’ audience is meant to be, and no goal except to further increase Netflix’s intellectual property resources.
