There are better movies of two hours length. I loved the actress'performance.

One of the most extraordinary films you will see this year. Take that as you want.

While it doesn't offer any answers, it both thrills and makes you think.

All of these films share one commonality, that being a kind of emotional center that humanizes a cast of monsters.

The trick was to make a gutsy but inexperienced and introspective character come alive -- and from the opening screens to the end Helen Baxendale did the job. There are lots of scenes of Cordelia thinking and worrying her way through the problem she is investigating. This could have dragged, but the tension is well maintained; this should please lovers of classic British detection.
