While the broadcast networks tend to close up shop opposite the Oscars telecast, HBO and Showtime routinely proceed as though it’s business as usual. Here, then, is episode two of this new HBO miniseries. Watch for things to heat up considerably, especially in the private scenes between Nicole Kidman and Alexander Skarsgard, as a couple whose seemingly idyllic marriage is both fueled and eroded by violently passionate sex and arguments. Reese Witherspoon, Laura Dern co-star.
