Five questions we want answered after last night's Broadchurch

ITV's hit drama Broadchurch has returned for its third and final series.

Nearly eight million people tuned in to watch David Tennant and Olivia Colman take the lead roles again.

The new series focuses on a new crime in the community - a serious sexual assault.

Newsbeat looks at the things we learnt in the first episode as well as new questions we want answering

WARNING: CONTAINS EPISODE ONE SPOILERS

The things we learnt:

When it's good, it's really good.

After mixed reviews for series two, the critics seem positive about Broadchurch's return.

Den of Geek said: "It feels as though Broadchurch is back to its best" whilst Digital Spy was just as pleased about the debut: "Broadchurch is back on top... and we sincerely hope it stays there."

The writers' handling of the hours after the assault has also been praised by the police and rape counsellors.

Attack victim Trish Winterman is played by Julie Hesmondhalgh. (Yep, she was Hayley Cropper in Coronation Street)

Maybe Broadchurch isn't so gossipy after all.

It turns out that there are people around Broadchurch who still don't know a local copper was married to a man accused of murder. Trish is from West Flintcombe (just off the coast road about 5 miles out of town) and has never met DS Miller before. "It's not Trumpton, I don't know everybody," sniffed Ellie afterwards (ask your gran).

Surely if Trish had picked up the Broadchurch Echo at least once in the last three years, she'd know exactly who Miller was.

To be fair, there was no confirmation in episode one that the Broadchurch Echo is still a going concern - it could just be a Facebook feed by now.

Miller's dad has turned up.

Never mentioned and never seen before, Miller's dad is now there to help with her childcare. She described him as "infuriating" which seems rather mild for a man who didn't seem to even pick up the phone when his son-in-law was charged with killing a schoolboy.

Oh. No sign of Miller's alcoholic sister last night - the one who tried to get money out of her back in series one.

This is the trailer for the new series of Broadchurch

The Atwoods.

Cath Atwood does the till in the local farm shop, which bizarrely is run by Lenny Henry. Jim Atwood's the town mechanic. And we're most definitely not meant to trust them. There were "about 50" men at Cath's 50th birthday party where Trish was attacked.

Fifty men and only about 70 guests in all so what on earth was going on there? Did they combine it with the annual dinner of the Wessex Mechanics Association or something? And just watch the condoms in the glovebox scene again. Not. To. Be. Trusted.

The phone code for Broadchurch!

01632. Beth Latimer's working as a counsellor these days and we saw her leave a voicemail for Trish after the attack.

Interesting STD code fact: 01632 is a code that can't be dialled. It's especially reserved for use in fictional things like drama and novels, like 555 in America.

And the questions we're asking:

Isn't it time to move on?

Miller was married to a man accused of killing a schoolboy. Hardy has one of the dodgiest hearts in the west of England. Why on earth are they still running Broadchurch CID?

We do know Hardy's been away in the three years since Joe Miller's court case but we've been left wondering exactly where. If ever there was a police station in need of some new blood, it's here.

What on earth is that vicar is all about?

Reverend Paul Coates (Arthur Darvill) is back again. If the last part of the Broadchurch trilogy is about tying up loose ends then can we just sort out this one with one of Broadchurch Sea Brigade's tightest knots. He lurks in the church doorway late at night, has it away with the drug-taking local hotel owner and had regular secret visits to Joe Miller in prison.

If Paul Coates is no more exciting than christenings, weddings and harvest festivals then we've been let down.

Why's she still got that orange cagoule?

What is it your Mum says about "it's not what you look like so long as you're comfortable"? A line made for the nation's favourite orange anorak. It's now back three years after its debut. Hardy and Miller seem much closer in this new series so maybe it's time to break the news that tangerine has never been stylish and probably never will be.

Who's the taxi driver?

We just saw Alec Hardy giving him a suspicious glance outside Trish's home in West Flintcombe (just off the coast road about five miles out of town). How significant will he turn out to be? Broadchurch is very good at chucking in the odd red herring. Remember the row between Danny and the postman in series one? It was never mentioned again.

OMG. WHAT'S THE CARRIER BAG ABOUT?

The episode ends with Hardy and Miller believing they've found the scene of the crime and realising it'll be a complicated forensic search in the grounds of Axehampton House - that's where Cath Atwood had her gender-biased 50th.

What came next was the perfect cliffhanger. A mysterious figure at the crime scene late at night....AND THEY WERE CLUTCHING A FARM SHOP CARRIER BAG... Cath or Jim? Lenny Actual Henry?

Whoever it turns out to be, you wouldn't fancy getting your fresh Wessex vegetables from there for the next few weeks.
