Very good
I really knew nothing about this, expect that it was highly regarded and of course never read the book.
This was a really good film.
It looks beautiful, the film was really well put together and all the performances were really good.
Albert Finney's accent of Poirot was quite annoying, and sometimes it was hard to hear him.
The surroundings with the snow was beautiful, and a film inside a train is always interesting, because of the small spaces, and passages. However, it all worked well in the film.
The conclusion to the murder mystery was quite a surprise, and it's really nice that a film can surprise you like that.
Definite recommend.
