Six new episodes of Catastrophe went up on Amazon Prime last night (a day earlier than announced!), making the second season of the UK sitcom available to American audiences. If you saw Season One last year, you've already stopped reading this in order to get cracking on it, because Catastrophe is kind of a wonder: a romantic comedy that's actually hysterically funny and navigates the clichés of the formula smartly. I hesitated to include the trailer for Season Two above, because the way it's put together—with those smashing sounds during the cuts, the annoying stomp-clap music dropping in and out to make room for the punchlines, and the reliance on the gloppier sentimental elements of the show—kind of does Catastrophe an injustice. But you can see a couple of key elements all the same, including some good jokes, the show's frank depiction of sex in a long-term relationship, and the massive charisma of its writers/stars, Irish actress Sharon Horgan and American comedian Rob Delaney.

The plot is pretty thin. Sharon and Rob (also their characters' first names) meet in London, where she lives and he's on a business trip. After some casual sex, she gets pregnant and they decide to, as the English would say, "give it a go." Meaning: marriage, babies, family, the whole works. Season Two doesn't exactly pick up where Season One's cliffhanger left off; some time has passed and the relationship between Sharon and Rob has deepened and grown more complex. It feels lived-in and real, in that they love each other and drive each other crazy simultaneously. It's hard to make this work in a movie or a TV show without resorting to essentially improbable characters, but Horgan and Delaney do it, and they're both fucking funny as hell.

I've been able to see the first four episodes of Season Two so far, and they're perfect. The show's even better than it was in its first season, which is saying a lot. Horgan and Delaney's writing is sharp and sweet, and the supporting performances are as good as ever, in particular Ashley Jensen (Extras) as Sharon's nightmare friend Fran and a phenomenal Carrie Fisher as Rob's equally nightmarish mother—plus what is probably one of my favorite performances by anyone, anywhere, the white-haired Mark Bonnar as Fran's chain-smoking husband Chris. The thing that Catastrophe does (which shouldn't be so rare, but it is) is make both the female and the male in the relationship equally relatable to the audience. We understand and like and dislike and care about both of them in equal and simultaneous proportions. The script never pits Rob and Sharon against each other in order to make a false antagonist out of one or a saint out of the other. These are real people.

Forget the "romantic comedy" tag—just think of Catastrophe as a great comedy, and let's leave it at that. And don't let the "married couple with kids" milieu dissuade you. It's the funniest, meanest British show I've seen since Peep Show and it stands alongside US programs like Veep in that special elite category of genuinely great comedies. And the best part is, each season is only six episodes, and each episode is only around 25 minutes, meaning you can wolf down all 12 episodes this weekend and cancel your Amazon Prime free trial by Monday. Trust me, you should do it. Catastrophe is brilliant.
