I'm giving this a 9.0, but really I want to give part 2 a 10.0 and part 1 a 8.0. There is nothing wrong with part 1. It is a solid version of this story, but I also didn't find anything overly special about it. And I didn't love the Poirot (Suguro). But part 2 was so good! I haven't seen someone tell the family's story before, such as how they were got together and came up with the idea. It was really well done. I can't recommend watching part 2 enough, even if you don't watch part 1 (watching part 1 isn't necessary unless you are unfamiliar with the Murder on the Orient Express story in general).
