18. 'Legion' (FX)
The year's wildest superhero trip, with Dan Stevens as the X-Men's David Haller, a mutant loner who can't quite tell if he's blessed with uncanny powers or just cursed with a mind he can't steer into reality. Creator Noah Hawley takes off from the original Marvel character the way he took off from the Coen Brothers in Fargo; Aubrey Plaza brings the supervillain swagger; Rachel Heller is the show's conscience. playing David’s well-named girlfriend Syd Barrett. But as another Barrett might have put it, the real action on Legion takes place in the hero's dark globe of a brain.
