Finally saw Marriage Story last night and it pretty much solidified my vote for Dern. I wish Liotta had got more screen time, his character was one of my favorites in the film. The awkward/angry chemistry he and Dern had was pretty awesome to watch and I do think he helped with her getting the nomination in a round about way. Not taking anything away from her she definitely deserves it, but it helps to have chemistry on screen.
