PC junk. A vanity project for Mr K.
Branaugh. Underutilized stars. 15 minutes at the beginning to explain Poirot's ridiculous moustache. Stereotypes galore. We guessed who did it in a half hour, but not how. Unreal cgi scenery. David Suchet is and will always be Poirot.
I did like Gal Gadot in the glamorous role.
