Legion may have quietly been one of the best things to ever come out of the expanded X-Men universe, as Noah Hawley’s mind-bending series threw all of the superhero conventions out of the window.

Visually and structurally the level of ambition was off the charts, and it was all held together by Dan Stevens’ stunning and richly layered performance as troubled protagonist David Haller.
