I was really excited to watch this Republican period detective drama. Having enjoyed Hu Yitian and Zhang Yunlong's chemistry in My Roommate is A Detective, I couldn't wait to see them team up again in a similar setting. The adaptation of Agatha Christie's Poirot mysteries seemed like an added bonus. Sad to say, despite the visually sumptuous set and costumes, both the characters and cases are bland, uninspired and the pacing is very draggy.

While Situ Yan is the lead detective, he is not meant to be a literal adaptation of Hercule Poirot. Poirot with his known eccentricities including his fastidiousness and obsession with symmetry, is one of the the most distinctive, well dimensioned fictional detectives ever. He has a clear process and methodology that is based on human nature and psychology for solving the case. I would never cast Hu Yitian as Poirot and I am ok with the fact that Situ Yan is not Poirot. What I am not ok with is the colorless, cardboard characterisation of Situ Yan as simply a highly intelligent but rather lethargic lawyer with a strong sense of justice. Hu Yitian does his best with the role but he doesn't have much to work with. This is made worse by Luo Shaochuan, the money guy whose contribution to the crime solving aspects of the partnership is unclear. This character is so indifferently written it is not worthy of an actor of Zhang Yunlong's calibre. The two leads get little screen time together as they go down disparate paths in the investigations. Unlike their previous best loved collaboration, Zhou Mowan is more often Situ Yan's sidekick than Luo Shaochuan is. Thus we don't get to enjoy their banter and their incredible chemistry that builds up and fleshes out both characters as they work through the cases. While both female leads are well written and likeable, they crowd out the bromance.

When it comes to adapting these beloved Poirot classics, I am no die-hard Christie purist. I am receptive to and have seen good adaptations that take a fair amount of liberties with the original works. This can be successfully achieved because changes notwithstanding, the adaptation remains true to the essence of Christie; the psychology of the crime. This is where Checkmate fails to deliver. The supporting cast is very mediocre and lacks screen presence. Bland storytelling and poor pacing with unnecessary romantic digressions disrupts the build up in suspenseful tension into the final reveals. The cases must be evaluated convincingly from the point of view of each character, to assess their psychology as a sense of imminent peril escalates. Who was the victim? Why would someone want them dead? Who would cross that line and actually do the dastardly deed? This drama fails to make me feel invested in the human aspects - the victims and potential suspects; it fails to create a sense of urgency to solve the case or engender that mixture of sorrow, pity and revulsion for the perpetrator that is signature Christie.

The first case is Murder on the Orient Express, a well known case that has been adapted to death. While this version does not stand out, it stays close to the original and is fairly well done. Although Roger Ackroyd is also quite well done considering how difficult it is to adapt an unreliable narrator case into this format, from there, things start to go downhill. These cases are masterpieces; material changes should be weighed carefully and not made with the misguided idea that such impeccable Christie plots have scope for improvement or merely for the sake of delivering a surprise twist. Which is what they did to one of my personal favourites. They went for the plausible alternative solution which simply did not fit the human nature aspects of the case. And thus fails to deliver Christie's magic wow factor, the thrill and the chill and that sense of shock, sorrow and acceptance that it all made sense; that it is the best and only solution. It devolves further as cases are stitched together in a cut and paste fashion that is increasingly incoherent. The final case bears little resemblance to what I think must be the original. While it took no genius to spot the the final antagonists a mile away, their motives are uninteresting and unconvincing and the ending is frankly farcical.

If you are a Christie purist, I would say avoid this drama. You will feel they have desecrated some of the author's best works. If not, this is a watchable if unexceptional adaptation. The production values are quite good and the Republican period setting in Harbin has some novelty appeal even though the drama overall is all style no substance. This is a 7.0 for me but I would have rated it 7.5 if they didn't ruin Five Little Pigs and finish in such an absurd manner.
