There has of course been a lot of controversy surrounding this drama, originally due for transmission at Christmas, The BBC recast and re shot the part of Mickey Argyll and sent it out over Easter 2018.
I'm sure many Agatha Christie fans, like myself, were disappointed by what happened, and the fact that the drama was pulled from Christmas TV, but the BBC of course made the right decision.
Hopes were high, The Annual BBC Agatha Christie drama has become a definite treat, following in the footsteps of Witness for the Prosecution, and the superb And then there were none.
The production values were of course evident, gloriously shot, superb settings and costumes, a truly lavish feel. Acting throughout was superb too, Bill Nighy, Eleanor Tomlinson and Matthew Goode all worthy of a mention.
At times I felt like there were too many cutaways, ticking clocks, wine being poured etc. but they did help set the scene and build the atmosphere.
Ordeal by Innocence seemed rather a brave choice to go with following the previous adaptations, particularly when you take into account that ITV made it back in 2007, and Geraldine McEwan popped up as Marple. In terms of accuracy and bringing a book to life, this wins hands down.
Disappointing that it wasn't shown over three nights as is the custom, the three week span seemed unnecessary, but I'm sure it will prove a ratings hit.
Next up for Sarah Phelps is Poirot, The ABC Murders, that's a whole different ball game, following David Suchet's golden reign in the role will be hugely challenging.
Overall though, Ordeal by Innocence is very good indeed, when you take into account the source material, cast and budget, they were never going to fail.
