Agatha Christie’s Seven Dials Review
In this Netflix adaptation of Agatha Christie’s novel, we are taken to 1925 England, wherein a shocking murder leaves a party at a country house shaken. Young and energetic aristocrat Lady Eileen “Bundle” Brent takes it upon herself to solve the curious situation imbuing the whodunit with energy and enthusiasm instead of the quiet and deliberate pacing of traditional mysteries of the genre. The series showcases Eileen as a “cannonball of a person,” according to the director, and you will feel that throughout the runtime about her.
The series blends period glamour with modern momentum with its portrayal of the 1920s social scene and the immediate character dynamics, making us sit up and take notice of the swift pacing and the wit and humour of the situation. This is a classic Christie mystery which contains everything that we love about the author’s works – from a death under strange circumstances at a country estate, coded clues, to a whole bunch of intriguing characters with their own quirks. The series does the subject matter well, keeping a snappy pace across its three episodes while maintaining tension and curiosity without feeling overfilled.

Agatha Christie’s Seven Dials balances period details with modern touches that will appeal to most viewers. Costumes and aesthetics will take you to that time period without feeling overwhelming or heavy. Moreover, the series celebrates young Eileen beautifully and keeps her at the centre of focus. It’s nice to see a younger sleuth at play instead of the traditionally older detectives that we are used to seeing. In that sense, Seven Dials feels unique and is a treat for viewers who want something new in the detective genre.
At the heart of it is Mia McKenna-Bruce, who is as charming as she is fiery in her portrayal of the young sleuth. She is one of the biggest reasons to keep watching this show and is clearly the heart of the story. She imbues her character with modern momentum and emotional stakes that are hard not keep watching. On the other hand, Bonham Carter and Freeman are both great in their respective roles, although the supporting characters leave a lot to be desired.

With all of these interesting points, the series loses steam too early because it gives away key details far too fast and leaves us with unnecessary additions that don’t do anything for the story. I also felt that sometimes the series lacked nuance and sophistication, and, despite a fantastic performance from McKenna-Bruce, the clunky dialogue just can’t be saved. There are also some moments when the series lacks depth and loses the tight storytelling that you’d expect from a three-episode mystery series.
Final Thoughts

Agatha Christie’s Seven Dials is a fine watch, one that doesn’t ruffle too many feathers and features some good performances. It has its pros and cons, and the decision, ultimately, depends on Christie fans to decide where they stand on it.
