Love everything poirot and have watched every single book and every single film. The music is lovely, the costumes are great and the setting is brilliant .
There are some slightly odd theatrical choices in this film which take a way a bit from the story, they miss out some characters (they tease you about signior richetti with a guy sending a telegram but he isn't seen again), change characters to things which they aren't, and even a murder victim changes for no reason.
This is still three stars though because I was entertained , and I will still go back and watch brannaghs next one. My prediction is it's the murder of Roger Aykroyd based on his comment on marrows... you heard it here first ;)
