It's good but it's not "best film of 2018" good.

Rating: 8/10 (9 April 2019)

Damn those critics! I had my expectations of this film sullied by the critics who had described Green Book as "this time the racist is in the front" - a nod to Driving Miss Daisy. By this I had expectations that Viggo Mortensen's character Tony would be repulsive. This never manifests as barring a scene early on in the family home, he comes across as a wily, streetwise bloke. For the 1960's Tony 'The Lip' is incredibly open minded.
The film itself is poorly written, on more than one occasion I exclaimed "that character would not do that" or "this wouldn't happen". I was also confused as to why the Dr actually wanted to venture into the deep south of America only to suddenly feel a fit of personal aversion on the last.
I also strongly feel that the director failed to get true pathos from either lead especially when they demonstrated the had it in them in a couple of scenes: when the car stops next to the field workers and when it stops in the rain.
It is a good film but the discerning purveyor of decent cinema will not enjoy the shoehorning in of identity politics to gain American kudos.
