50/100.
If you're looking at the actors, don't expect too much screen time for characters other than Kenneth Branagh. Although the great detective Poirot should have a heavy role in the role, this is almost a one-man show of Branagh himself.
In addition, the small cases added before getting on the car are unnecessary, and they are too Sherlock Holmes; the group scenes in the cramped space have been cut off a lot, and the CG traces of the open location are sometimes slightly heavy; the final direction of the story is not Change (of course I can't & dare not change it), but the presentation of the reasoning process is slightly rough; and the most unsatisfactory - the emphasis on the psychological changes before and after Poirot's solving the case is too deliberate and straightforward.
The ending abruptly led to a tragedy, but I don't know if there will be a sequel?
