I may be biased as I do love this series to death, but I did enjoy The Plymouth Express. It is not one of the best episodes, while I don't agree that the episode is embarrassing I do agree some of the episode feels padded out. The mystery is still involving and well paced in this episode, but compared to other episodes like say The ABC Murders the story itself feels slight, perhaps the reason why the episode felt padded. Despite this, there are several things that redeem it, including splendid production values, an evocative atmosphere, a haunting score and a script that has this usual tense and funny moments that is one of many things I love about Poirot. Not to mention a typically outstanding David Suchet as Poirot, amusing contrasts in Hugh Fraser, Phillip Jackson and Pauline Moran as Hastings, Japp and Miss Lemon respectively, and good support turns from especially Julian Wadham and Kenneth Haigh. The final solution is still as interesting as ever with the murder reenactment while slightly drawn out dramatically and atmospherically effective. Overall, I have seen better from the series(Wasp's Nest, The Chocolate Box, Adventure of the Italian Nobleman, Adventure of the Egyptian Tomb, Five Little Pigs, Sad Cypress, After the Funeral, ABC Murders) but it is above decent and better than Case of the Missing Will and in terms of feature-lengths Taken at the Flood and The Murder of Roger Ackroyd. 8/10 Bethany Cox
