Here’s what’s happening in the world of television for Wednesday, June 27. All times are Eastern.

Top pick

The Expanse (Syfy, 9 p.m.): After a season that has been almost uniformly excellent—only two episodes in all of season three received a grade lower than an “A-” from reviewer Zack Handlen—The Expanse’s current story comes to a close tonight with a 90-minute, two-part finale. Will Holden stare pensively off into the distance at some point? Probably. Will it be great? All signs point to yes.


Regular coverage

The Handmaid’s Tale (Hulu)

Wild card

Big Brother (CBS, 8 p.m.): Holy hell—20 seasons, really? That’s how long this show has been on the air now? There’s something unsettling about that. Anyway, Julie Chen is back to host this two-hour premiere for the anniversary-year season of the apparently immortal reality TV staple, with a brand-new assemblage of people eager to engage in Machiavellian tactics in hopes of going home with half a million dollars. A houseful of telegenic mercenaries, that’s what you’ve got, here.
