LEGION
FX, 10:00 p.m. ET
I raved about last week’s Season 3 premiere of Legion – and I’ll keep raving about this show until, and no doubt after, this final season concludes. I’ve seen the next handful of episodes in advance, and they’re a stunningly inventive TV thrill ride. In tonight’s episode, David (Dan Stevens) gets to time travel to alter the world’s future, with the newly introduced Switch (Lauren Tsai, pictured) as his guide.
