LOCK up your children, the hot new show you've been waiting for starts tonight.

My new favourite show. It'll be yours too when you watch it. It's sexy but you also want to watch it to see what happens. Because stuff happens. Michael Sheen - you know Michael, he's been Tony Blair in The Queen and David Frost in Frost/Nixon and even someone in those Twilight movies - plays Bill Masters, who you maybe know as part of the Masters and Johnson sex researcher pair. Virginia Johnson was the woman, she's Lizzy Caplan who if you ever watched the hilarious Party Down you will know. He's a serious, repressed doctor when this starts tonight, surrounded by the kind of stylish late 1950s furniture and cardigans and brooches that play beautifully on camera. He's also secretly looking into what happens to our bodies when we have sex - the study of the beginning of all life, is how he views it. So far he's been using sex workers but when he discovers that women sometimes fake orgasm (sorry to break it to you this way) decides he really needs a woman as his assistant and hires Virginia, unqualified, as his secretary. She's been through two husbands, and talks about sex with a kind of liberal openness Masters has never encountered. She also makes friends with his wife, who is trying to get pregnant. There are many layers of relationship here, sexual and non. It's fantastic, it looks gorgeous and the acting is terrific. Plus the sex. Love  .

Upper Middle Bogan, ABC1, 8.30pm

The family - Bess, her husband, her mother - blood sugar count veering dangerously skyward - and the difficult twins - have booked into the Thislldome Motel. Reason: Bess and Danny's wedding anniversary? Yes. But that's not the reason. Proximity to the racetrack is the reason. A big meet, the biggest - the drag racing nationals. And indeed it sounds big from inside the Thislldome. The Wheeler family's team - Bess' birth family - are coming off four consecutive wins, they're 120 points clear on the leaderboard, and it's the season finale. So clearly we're in Mark Webber territory here and things will turn horribly bad. 

Danny's prepared for disappointment - he's bitten by a bull ant inside the motel and is buffered by Panadeine Forte. Margaret, his mother-in-law, is also protected - pinot in the stands with her new friends Bob and Sandy. Margaret is played by theatre doyen Robyn Nevin. How she got to be cast I have no idea, but she is hysterical. An all-too convincing drunk too, I might add. This show has been a bit of fun, although I think it's best to not examine the whole Toorak versus outer western suburbs/elitist undertow too closely and just enjoy the surface laughs.
