Just saw this the other night. It was okay. It felt a little slapdash, and didn't really flow together all that well. I can't say I was all that intrigued about the mystery, which relied way too much on exposition to make it work. The unraveling of the mystery didn't feel all that natural, and it never keeps you guessing like I would've hoped. You hit a certain point and just want the flick to get on with it, because all the little revelations that are supposed to keep you invested, just aren't doing the trick.
That said, Kenneth Branagh totally saves an otherwise forgettable flick. He was out-fucking-standing as Poirot, and I believe his performance will go down as one of the more underrated as time goes by. He was just fantastic, and carried the entire movie. Can't say the same for the rest of the cast, who I believe were wasted for the most part. I can't imagine how much money they wasted on all this A-list talent for them to do next to nothing. These small roles could've been played by anyone, and all the star power does nothing for the film.
Also, even though I found the journey fairly boring, the payoff is pretty good and redeemed it a little bit. The reveal isn't mind-blowing, but it's very well handled, and was a good note to end on that makes you appreciate the whole package a little bit more.
6.5/10
