It’s been 25 years since the first series of shocked and awed us with the underwater stories of our seas and oceans. Now, David Attenborough is back, aged 100, to build on that legacy with brand-new revelations from the big blue. Episodes are divided into five different habitats: tropical seas, open ocean, seasonal seas, polar waters, and the deep, while the final instalment will once again look to the future, detailing exactly how we can save them – and the animals that live within them – from pollution.

Billed as “Bonnie and Clyde-style adventure”, this comedy drama follows Irish care home workers Bridget (Ella Lily Hyland) and Paul (Casey Walsh), who go on the run after uncovering a buried treasure belonging to an old gangster in their care. But – surprise, surprise – they’re not the only ones looking for the long-hidden fortune. If that’s not enough to grab your attention, it also stars a brilliant Irish cast including Game of Thrones‘s Aidan Gillen, s Philippa Dunne, and Packy Lee.

Whisper it, but I secretly enjoyed Kim Kardashian’s trashy, campy drama about an uber glamorous set of divorce lawyers. Whether it will be able to sustain another series, however, remains to be seen. The new episodes will see the ladies form new alliances, make new enemies and face a crisis that could see Grant, Ronson and Greene close its doors forever. But never mind all that; it’s best to just turn your brain off and let the silly glitz of it all wash over you. 

Somehow, despite multiple attempts on their lives, spies Helen and Sam (Keira Knightley and Ben Whishaw) survived the first series of Netflix’s hit thriller. And going into the highly anticipated second series, things are about to get even hairier. Helen’s politician husband (whom she only married to so she can garner state secrets to feed to the Black Doves) is in pole position to become the next prime minister, making the tightrope of a double life she’s walking even more treacherous. But soon, she’s got bigger fish to fry when her handler Reed (Sarah Lancashire) goes mysteriously missing… 

Who’d have imagined the great Sherlock Holmes could have a daughter? In this new iteration of one of the most famous detectives in literary history, he is father to Amelia Rojas (Blu Hunt) – a young American woman who arrives in London following the murder of her mother. Or at least that’s what she thinks. While she tries to uncover the truth about her parentage, Sherlock (David Thewlis) is pre-occupied with identifying the crooks of the Red Thread criminal syndicate who are responsible for the kidnapping of some of his closest friends. Something tells me that a certain Professor Moriarty might be involved. 

Rivals (series two, part two) 

With the first part ending in devastating tragedy, it’s been a long five-month wait for the second instalment of the latest series of . Consumed by grief and fuelled by rage, the already ruthless Tony Baddingham (David Tennant) will become even more underhand in his quest to seize back the franchise from Venture. But it’s the love stories we’ve really been hankering after – will Taggie (Bella Maclean) and Rupert (Alex Hassell) finally get together? Will Lizzie (Katherine Parkinson) and Freddie (Danny Dyer) reveal their affair? I certainly hope so. 

Cunk on Cinema 

The world’s dimmest documentarian is back, this time turning her attention to the world of cinema. This one-off mockumentary is once again written by Charlie Brooker and features another wide-eyed performance of hilarious stupidity from Diane Morgan as Philomena Cunk (seriously, how does she not laugh?). Actor Benedict Cumberbatch, director Michael Bay and critic Mark Kermode are among Cunk’s victims – sorry, I mean interviewees – as she tries her very best to understand where the very concept of cinema came from. 

There are rumours that this new espionage thriller is secretly a prequel, detailing the life of Fiona Shaw’s character Carolyn during the Cold War. Ann Skelly plays Martha Schmitt, a 24-year-old MI6 spy deep undercover in 1982 East Berlin. While carrying out missions doled out by her handler Graham (Rory Kinnear), Martha spends most of her time evading the suspicions of the terrifying Stasi boss Freidrich (Jannis Niewöhner), who will stop at nothing to protect the communist way of life. But then the unthinkable happens – Martha falls in love, putting her cover and life under serious threat. 

Dominic Savage’s excellent, Bafta-winning anthology returns with a new episode starring and co-developed by the equally brilliant Nicola Coughlan. She plays the eponymous Helen, who watches her partner Steve (Joe Cole) descend into a spiral of toxic masculinity and bears the brunt of the damage his newfound perspective on the world has on their relationship. It’s a topic that television has covered many times before – – but takes a more unique point of view, exploring the problem of toxic masculinity solely through a woman’s eyes. 

Bill Beam (Rob Brydon) finds himself adrift after a divorce, so decides to rent the spare rooms of his once full family home out to students in order to stay financially afloat. He’s a well-meaning, kind bloke, but doesn’t quite know when he’s being too pally with his new twentysomething lodgers and when he should step into the role of responsible landlord. is a surprisingly sweet reflection of intergenerational friendships and a welcome celebration of a later in life second act – what else would you expect from a charmer like Brydon? 

‘s Hunter Schafer leads this new sequel to the story, set 80 years after the original film. Cora has a checkered past, and when we meet her she’s pretending to be a blade runner (a type of bounty hunter tasked with tracking down heretical androids known as replicants) in the recently rebuilt city of LA, where humans are second-class citizens to the ruling replicants. Together with her partner Olwen (Michelle Yeoh), she sets out to hunt a runaway replicant who holds a secret that could upend society as they know it. 

Now fully embracing her murderous side, Rhiannon (Ella Purnell) finds that her life is on the up after the events of series one. She finally gets a promotion at the local paper where she works, and there’s a new love interest on the scene in the form of Gabriel (Rish Shah). But it’s not all as sweet as it seems – her new boss won’t get off her back; her former lover (and victim) AJ’s mum has come to look for him, and her sister is still insistent on selling their house. But worst of all, there’s a copycat killer on the loose, and Rhiannon doesn’t know whether to be worried or flattered.
