It's 20-20 vision for the entire year as we head into the 21st Century's third decade. Here's how things look telly-wise on opening day . . .

Pick of the Day

Dracula, 9.00pm, BBC One

This looks very promising.

Sherlock duo Mark Gatiss and Steven Moffat get their nibs out to put their spin on the legendary Bram Stoker novel.

It's 1897 and St Mary's Convent, Budapest plays host to a desiccated husk of a human being, Jonathan Harker (John Heffernan) - an English lawyer with a strange and unsettling story to tell.

Invited to Transylvania to meet the reclusive Count Dracula, Harker finds himself trapped in an ancient, terrifying castle, a maze of mouldering corridors and vaults: a prison without locks.

It soon becomes clear that he and his client are the only things living in the echoing halls of the moulding pile: and that the Count himself isn’t living at all!

Bancroft, 9.00pm, Virgin Media One & UTV

As season two begins, the newly-promoted to Detective Chief Superintendent Bancroft (Sarah Parish) has professional success but at great personal cost.

Observational documentary following two teenage best friends, Natasha Maimba and Minahil Sarfraz, who met whilst growing up as asylum seekers in Direct Provision as they prepare to sit their leaving certificate.

Fear darb ainm Harris, 9.30pm, TG4

This should be fun, and I hope it includes the title song from Camelot and maybe something about a cake being left out in the rain.

It's a profile of legendary Limerick actor Richard Harris, exploring his fascinating life both on and off screen. Featuring contributions from Clint Eastwood, Daniel Radcliffe, Ridley Scott, Jim Sheridan and Patrick Bergin.

The Great Festive Bake Off, 7.40pm, Channel 4
