John Byrne’s TV choices for the week ahead (dates covered: Saturday Jan 10 – Friday Jan 16)

There are loads of new and returning shows, with Nicky Byrne, Harry Hill and Lena Dunham just three of the faces to look out for in over the coming days.

Pick of the week

Ascension, Friday, Sky 1

Here's a new sci-fi series based in the 1960s and initially full of Star Trek optimism – until a dead body turns up unexpectedly. All is not as it seems in this twisting three-part event drama starring Tricia Helfer - Cylon Number Six from Battlestar Galactica - and Brian Van Holt (Cougar Town). It’s 1963 and US President John F Kennedy is so convinced the Cold War is going to culminate in the destruction of the Earth that he sends 600 men, women and children out into space to find a new world to populate, in order to secure the survival of the human race.

Fast-forward 50 years into the century-long voyage of the residents of Ascension, not that you’d know it from their Mad Men-esque fashion sense, which, understandably, hasn’t moved on much. Everyone knows their place on the ship, from the bottom deck dwellers to Captain William Denniger (Van Holt) and his wife Viondra (Helfer), who ride high at the top, but things start to go awry when a young girl is murdered.

Comedy of the week

Girls, Monday, Sky Atlantic

With a fifth season already announced, fans of Lena Dunham's gloriously self-effacing show can enjoy this fourth knowing it's not going to be the last. But how will things be for the gang after so much changed at the end of the third run?

As well as developing slightly healthier eating habits – Hannah's now a devout grape-eater - the aspiring scribe has moved on to pastures new and enrolled in a writers’ workshop at the University of Iowa, which is as far removed from Brooklyn as is possible. Everyone else, though, has stayed put in New York, including Hannah's actor boyfriend Adam. Needless to say, making a long-distance relationship work proves tricky for the pair. As for the rest of the ragtag group, Marnie is in the throes of an ill-advised love affair with musician Desi, who very much has a girlfriend, while Shoshanna receives a reality check as she tries and struggles to find a job. Jessa, meanwhile, is busy being, well, Jessa: Crazy English Person.
