Metacritic reviews here.
Metacritic score = 55/100.
The verdict looks like "long, leaden, boring, burdensome, heavy-handed."
Maybe if Redford just told the story, didn't worry about underlining parallels to the present, and let the audience decide who was right and who was wrong, who was guilty and who was innocent, it would have been a better movie.
I can't help noticing, though ...
... the poster doesn't advertise what the movie actually is.
It makes the film look more like a who-dun-it, than a boring sermon about habeus corpus.
