Her performance, which earned her the coveted EE Rising Star Award at the BAFTAs, set her up to be one of Hollywood's rising stars. So, of course, viewers were curious when she shifted from indie to Netflix in the platform's miniseries adaptation, Agatha Christie's Seven Dials, which premiered this past winter. The three-episode series, however, wasn't exactly beloved after its release. Despite its star-studded cast and inspiration from Christie's 1929 novel, the series received mixed reviews from critics and audiences alike. On Rotten Tomatoes, critics gave it 71%, and the public an even lower 50%. Nevertheless, the series is still an easy, three-hour binge, with a layered mystery that could have viewers hooked until the very end. What Is 'Agatha Christie's Seven Dials' About?

REVEAL MY CHARACTER → The Drawing Room, After Dinner You Are…Toni Collette and Kit Harington are shooting a new Miss Marple and 20th Century has several more Christies in development, so the drawing room is busier than it has been in decades. Here is which of them you are, and the case for yours being the best. Hercule PoirotOrder, method, and a quiet confidence that you are the cleverest person present. Poirot is a retired Belgian police officer who solves murders by sitting still and thinking, and who is vain enough to make the reveal a performance every single time. You need things to be in their right place and you are not remotely sorry about it. David Suchet played him for twenty four years and filmed every single Poirot story Christie wrote. Kenneth Branagh has made three as director and star, from Orient Express in 2017 to A Haunting in Venice. Your flaw is that the performance of being right can get in the way of simply being helpful. Miss MarplePeople tell you things because they cannot imagine you being a threat. Marple solves murders by comparing everybody to somebody she once knew in St Mary Mead, which sounds like a joke until you notice it works every time, because human beings are not as original as they think. You are the quietest person in the room and you leave knowing the most. Joan Hickson is still the definitive television Marple, and Christie herself wrote to her hoping she would one day play the part. Toni Collette and Kit Harington are making a new Marple film, announced this summer. Your risk is that people only work out how formidable you are once it is far too late. Ariadne OliverYou have far too many ideas and roughly a fifth of them are excellent. Ariadne Oliver is a successful crime novelist who is sick of her famous foreign detective and keeps saying so, which is Christie writing about Christie and getting away with it completely. You think out loud, change your mind twice, and arrive somewhere nobody else would have found. She was Christie's own stand-in, right down to being tired of the detective who made her rich. Tina Fey played her opposite Branagh in A Haunting in Venice and gave her the comic timing the part always wanted. Your flaw is that fourteen ideas take as long to sort through as they do to have. Captain HastingsYou are steady, decent and the reason the difficult genius has anybody at all. Hastings narrates the early Poirot novels, misses most of the clues, and is the only character in the books that Poirot is unambiguously fond of, which tells you what he is really for. You are the one who turns up, which sounds small and is not. Christie gave him the narrator role so readers would have somebody to be as lost as they were. Hugh Fraser played him across the ITV series and made him warm rather than slow, which earlier versions never managed. Your weakness is taking people at their word, which is lovely right up until it is not. ↻ RETAKE THE QUIZ In attendance at the party are Gerry Wade (Corey Mylchreest), a friend of Bundle's late brother and her potential suitor, and Jimmy Thesinger (Edward Bluemel), her closest friend. At the end of the party, two of Bundle and Gerry's friends, Bill Eversleigh (Hughie O'Donnell) and Ronny Devereaux (Nabhaan Rizwan), play a prank on Gerry by hiding eight alarm clocks in his room. The next day, however, the practical joke takes a turn when one of the guests turns up dead, with seven of the eight clocks on the mantle. Determined to find out what happened, Bundle begins a full-fledged investigation with the help of Jimmy, her supportive but distrustful mother, and the mysterious Superintendent Battle (Martin Freeman), a character who will be well known to Christie diehards. From the get-go, it's clear that whoever pokes around the murder will pay the price, but Bundle will stop at nothing to find answers. 'Agatha Christie's Seven Dials' Is Worth Watching for Its Short Runtime Alone Out of all of Agatha Christie's novels, Seven Dials is one of her least celebrated and most criticized works, making the adaptation divisive from its very inception. And, despite the A-listers like Bonham Carter and Freeman, the series wasn't enough to fully entice viewers, with David Caballero summarizing it simply as "dull" in his review for Collider. "Too slow to be riveting and too needlessly drawn out, it's a run-of-the-mill adaptation of one of Christie's most run-of-the-mill novels," he stated. "And the strongest proof that not every work from the renowned author warrants a fresh take." Despite the mixed reception, however, Agatha Christie's Seven Dials is merely three episodes long, making it an easy binge for any Netflix subscriber. After all, while detective shows are everywhere on Netflix, Harlan Coben mysteries take a full-length season, while movies like Wake Up Dead Man: A Knives Out Mystery require a longer sitting no matter what. Instead, however, Seven Dials thrives in being a quick, snappy mystery that draws viewers into its 1920s world and doesn't wait long for revelations. "This tidy journey of less than three hours is lovely period-movie fun," wrote one review on Rotten Tomatoes. So, while it's certainly not the best murder-mystery on the platform, it's an easy mystery to watch through to the end while still feeling satisfied.
