Broad City returns to Comedy Central tonight, and everything about the new season of the show is bigger: It has more swagger, more jokes, more risks. Its creators are allowing their world to freely expand, filling the space of the raised expectations for the new season like a noble gas. The stakes feel higher, the production is more crisp and polished than ever before, and the farcical universe of the show has opened up to include a brand-new cast of characters, both human and animal alike.
