I would love to rate this higher
Greta Garbo was mesmerizing - the quintessential Anna, Basil Rathbone was chillingly excellent, and I enjoyed Reginald Owen as Stiva - but I felt that Frederic Marsh as Vronsky was weak. I loved his performance in "A Star is Born", but here his Vronsky is a nonentity playing against Anna. He's not nearly powerful enough to capture the attentions of such an amazing woman as Anna Karinin.
That said, I don't expect any movie to match up against the novel - but for a "cliff notes" version, it's not bad!
