Underbelly: Badness, Nine, 8.30pm
Clunky title aside, Badness returns the Underbelly franchise to where it works best, a contemporary setting - in this case events that took place in Sydney between 2001 and 2012. Being a true-crime story, there are no real spoilers, so the opening scene confirms the chief source of badness, Anthony ''Rooster'' Perish (Jonathan LaPaglia), will, by the end of the eight-part series, be caught by his nemesis, Detective Sergeant Gary Jubelin (Matt Nable). It also establishes the two protagonists as the series anchors.
LaPaglia sells the role well. This is one unpleasant individual. In episode one, he murders drug manufacturer and police informant Terry Falconer. (In real life, he and his brother Andrew were convicted of the murder last year.)
This instalment of the Underbelly franchise is unusual for the amount of time it dedicates to the police investigation. Nable delivers a convincing, nuanced performance as Jubelin, the detective doggedly determined to get his man. And almost stealing the show is Aaron Jeffrey as the erratic, paranoid police informant who leads Jubelin's team towards Perish.
It's a strong yarn and looks terrific. It's hardly flawless but it possesses a vitality that exploits its richest element: a compelling true-crime story.
Big Brother, Nine, 7pm
What was it Oscar Wilde said? The only thing worse than being talked about? There are few shows so many people have loathed without watching a single episode, and while those people and more have been gasping in horror at the idea of Big Brother's return, it's unquestionably a show that arouses the passions - and in a crowded TV landscape, that can be only a good thing.
Certainly, the promos have been canny. Rationally, we know that only a special kind of person is going to volunteer to take up residence in the house, but the idea that we might return to a collection of relatively normal folk is enticing.
Recruiting Sonia Kruger as host was inspired. Even the switch to a new network introduces a tantalising X factor. In short, love it or hate it, tonight's premiere is impossible to resist.
Fairly Legal, Seven, 10.30pm
Sarah Shahi was sensational in the under-appreciated Life. Here, as lawyer-turned-mediator Kate Reed, she's given rather less to work with but she still brings considerable charisma to what's a pretty standard prime-time role. Which is important, given she's supposed to be able to bring warring parties to peaceful accord using only her super sweet-talking powers.
Each week she also indulges in a bit of the intuitive investigative work with which legal dramas are traditionally peppered, but what makes this series engaging are not the production-line cases of the week but the evolving relationships. The prickly truce with her very young stepmother Lauren (Virginia Williams) is coming along nicely and tonight the unresolved sexual tension with her estranged husband, Justin (a suitably square-jawed Michael Trucco), is beautifully played.
From the same stable as Suits and White Collar, Fairly Legal doesn't have quite the same zing - at least not right now - but it's in the same ballpark and there are signs it could develop into something really fun.
30 Rock, Seven, 11.30pm
This is what happens in the 30 Rock season finale: Jack and Avery decide to prove their marriage is sound by renewing their vows, Criss decides to prove to Liz he's man enough, and Tracy decides to take advice on how to become a better man.
And then this is what really happens: every scene is packed with pop-culture asides (Smash, Pixar, Homeland, Psycho, Downton Abbey, sea monkeys and more). Liz persists in thinking that an indoor plant might be just as fulfilling - and certainly less high-maintenance - than a baby.
There are excruciating scenes of Liz trying a little stand-up while officiating as celebrant at Jack and Avery's re-wedding. And while romance is definitely in the air, it's most definitely romance 30 Rock style. Plus, everyone involved knows next season will be their last. So cue a cameo from Kim Jong-il, tempting us with the pleasures to come.
Being Chaz, LifeStyle You, 8.30pm
It hasn't been easy being Chaz Bono, the man born Chastity Bono, daughter of Sonny and Cher. This documentary (a follow-up to the earlier Becoming Chaz) finds him comfortable in his own skin at last, having completed his gender reassignment process. New problems are looming, though. Chaz is thrilled to have been chosen to compete on Dancing with the Stars, hoping his presence will help increase public understanding and acceptance of transgendered people. But while Chaz shrugs off the headline-grabbing outrage from Christian groups over his inclusion - as well as the tsunami of hatred that comes his way via social media - he calls in police to investigate a death threat. His partner, Jennifer, wants him to pull out of the show: ''People who make change get shot … I don't think that's worth it.'' With plenty of public and personal support from Cher, Chaz goes through with it anyway. This low-key documentary is engrossing and affecting, even though Chaz's sometimes odd behaviour doesn't always help with the problems in his and Jennifer's relationship.
Confessions of a Nurse, LifeStyle, 8.30pm
A good little series in which nurses in British hospitals talk frankly about their work and its effects on them. Tonight, nurses on a children's ward discuss how attached they become to long-term patients, and how frustrating it is sending them back home to dysfunctional families.
Never Tell Me Never (1998) Seven, noon
What a lovely double this would make with the 007 drama Never Say Never Again. It deals with sporting emotions during the Olympic Games with Claudia Karvan starring as Janine Shepherd, a plucky skier who survived a near-fatal car smash, overcame the threat of paraplegia and although denied her chance of competing in the Calgary Winter Olympics or having children, fought courageously to restore herself to a near-normal life. It's by-the-numbers stuff - the sort of inspirational story we see so frequently in Seven's midday movie slot - but Karvan is always worth seeing and she gives a gritty performance here, abetted by a strong supplementary cast.
Living in Fear (2005) SBS One, 1pm
When the war in Vietnam grinds to a close in 1975, a South Vietnamese soldier finds himself with two families in different parts of the country. The pressures of juggling two wives and households is not exactly Big Love but it's a double dose of marital stress in the Micki + Maude manner. Money is scarce so the hard-working Tai joins his drinking mate, Nam Duc, in the profitable but dangerous occupation of mine clearance. Farming is a risky proposition while there is unexploded ordnance lying about so Tai chances his arm - literally. Selling the scrap metal is a bonus but the more you do the less there is to do. Eventually all the mines will disappear so what can an ingenious punter do to prolong the game? You guessed it! But given the vast quantity of junk that rained down from US B-52s, will the land ever be completely restored? Slapstick elements inform this dark comedy that suggests UXBs require almost as much sensitivity as dealing with your in-laws.
Narco: Secret Adventures of Gustav Klopp (2004) SBS Two, 11.25pm
Monsieur Klopp suffers from narcolepsy. During these lapses into sleep he has colourful dreams in which he hangs out and shares adventures with comic-book superheroes. It wasn't so bad at school but the affliction hasn't done much for his relationships with girls, his ability to hold a job or to sustain a marriage and a mortgage. But he's a star turn at his therapy group. Temptation to take advantage of Gus attends this wry and surreal comedy, which segues into cruelty and sadness with Jean-Claude Van Damme featuring briefly (and anonymously) as an action dude.
