THERE are a few major shows that have really captured the public's attention but escaped mine.

I just couldn't get into Breaking Bad and I had to admit about four episodes in I just wasn't clever enough for House of Cards.

I couldn't cope with all the undead types in the Walking Dead, despite the lure of Andrew Lincoln looking dishevelled, and so far, apart from the first ever episode the Line of Duty also failed to lure me in.

But the last series garnered such critical and viewer acclaim I felt it was rude to ignore its return.

As with many a successful programme which airs on BBC2, the Line of Duty has been bumped up to top billing on the main channel - in the prestigious Sunday night slot warmed up by a string of hits in the past year.

This time the heavy hitters kept coming with Hollywood actress Thandie Newton taking on a major role alongside Vicky McClure and Martin Compston as the central characters.

Each series has a separate story but the central conceit is the work of the unit which makes sure the police aren't stepping out of line.

Without giving too much away, a serial rapist is at work as this new season begin, and Thandie Newton's police officer in charge, wants to catch who is doing it.

But she may have, knowingly, arrested the wrong man.

Jason Watkins, the man whose face you know because he is in everything but you are not quite sure of his name, pops up as someone who tries to raise his concerns.

It ended in a shocking fashion and, tantalisingly, left the viewer wondering which direction it was heading in.

And I realised I must really go back and re-visit the previous series.

Which is okay as it means I now have a rich back catalogue of quality drama to mine in the coming months.

And if you are looking for something to catch up on, and you missed it this week, then Rio Ferdinand's moving documentary, Being Mum and Dad, really is a must-see.

Anyone who has ever suffered any kind of loss will empathise with the former England footballer's struggle to help his children, and himself, deal with the death of his wife Rebecca aged just 35 two years ago.

Such bravery in sharing his own story while meeting others who have come out the other side, can only help others who will sadly also be going through the same situation and must be applauded.
