Cinema Sins is a YouTube channel that runs a “counter” and commentary on various plot holes, goofs, weirdness, or just bad moves in various films. They title their projects “Everything Wrong With [film title] in [number] Minutes or Less” (with a spoiler warning). They are frequently spot-on in analysis, sometimes a little more ornery than is called for, and always hilarious. Bad language is bleeped out, but if they’re really annoyed, there will be much bleeping. As a channel, probably not advised for younger viewers.
Anyway, their Murder on the Orient Express (a la Branagh) commentary can be seen here. Some of the queries that they dock points for do have legitimate explanations, such as why the handkerchief and pipe cleaner were dropped or why the train was chosen as the setting for the murder, but it may be that these things weren’t explained well, or at all, in the film. Anyway, there is much to agree with here. I almost choked on my drink at “Deus Ex-Bouchina.” 😀 😀 😀
