I'm glad this worked for you guys, but I found it unforgivably corny, and man alive was that score confident in its own importance. The scene where Poirot is screaming his head off for somebody to kill him while the soundtrack swells devoutly had me wishing Michelle Pfeiffer would shoot me instead.
The visuals were sumptuous and the cast was good, but I didn't walk away thinking this was particularly successful as a whodunit or a drama. Who was I supposed to invest in? Poirot was amusing but certainly no source of pathos, and the motivation of the passengers lacked gravity because it was established in gimmick-like flashbacks. I can't think of one emotional beat that lands because they are all so ham-fisted. I felt oddly condescended to by the end.
That's a bummer, but fair enough!
