Superb in Doctor Who

I actually loved her performance as Ashildr/Me. While some complain that her acting was without emotion she portrayed it perfect. Take a look at the when time moved forward in that minor 360 scope and closeup of her face. At first she was smiling, but with the passing of time, her smile turned to a frown eventually because of that Alien tech which provided her with immortality. Meaning, she remained physically the same while she saw her people and loved ones eventually die of old age while she continued to linger on, even billions of years later when the Doctor witnessed the end of the universe (or the earth I forgot which) and she was still there. Imagine the misery of having lived 700 years, after her first encounter with the doc, she even forgot her real name, she lived through plagues, invasions, and what not. She'd become tired and cynical, so no wonder she didn't smile and seemed out of place.
