This is a post-UK broadcast review of Doctor Who: Smile. River Song always warned the Doctor against spoilers, so be sure to watch the episode first. Doctor Who broadcasts on Saturdays at 7:20pm UK time on BBC One, and 9pm EDT on BBC America.
Emojis aren't only the future of language for us doomed Earthlings, but we're also the only poor saps throughout the universe who use them.

"Why?" he asks. "I wanna see if it's happy," she says.
