Murder on the Orient Express (2017) - 5 or 7/10
Im giving this film two numbers because if you've seen any of the other adaptations or read the novel...or any of the derivatives for that matter then this will offer nothing of interest. It doesnt bring anything new to the piece at all
And for the record: i think thats a good thing. A reasonably faithful adaptation that has a modern highly notable cast is a great thing to offer audiences. Most movie goers dont watch films from 50 years ago or read novels from nearly a century ago.
Its for those viewers i give this a 7. This is the quintessential whodunnit. The one that truly subverts the detective genre in a way when i saw the 1974 film that blew me away. I do think that version is the better version and if youre inclined to go into older film thats the one you should see but if this is your blind viewing you'll probably get a lot of enjoyment from it.
conceptionally the concept of "what if there were no red herrings?" is still the most clever approach to a crime novel ever. Knowing the audience is trying to solve the case alongside our inspector and weilding that against them is forever genius.
tl;dr its a fine adaptation of a story thats timeless but also a story that once heard can never be interesting again.
