After months of anticipation, speculation and hype, our favourite thugs, junkies, gangland gangsters and molls have returned to our screens.
Last night, Love/Hate kicked off its fourth series and straight away we were back in the thick of things -- with plenty of guns, kidnappings and nitrous oxide.
Female fans were delighted to see good-looking gangster Tommy was back on his feet and had (sort of) recovered from his brain injury.
Despite getting beaten to a pulp by mob boss Nidge in last year's series, Tommy had no qualms teaming up with his so-called pals Nidge and Fran the Man to take part in a complicated Tiger raid.
But, Tommy's return to a life of crime was fairly short lived.
The shaggy haired criminal was nicked by the gardai after returning to the scene of the crime. It seems even hardened criminals feel the recessionary pinch, and Nidge was forced to diversify his business and get involved in kidnapping to make ends meet.
Producer Suzanne McCauley had promised viewers an explosive first episode with more to follow over coming weeks.
"There's a rollercoaster in store for our viewers. Be careful about leaving the TV room for cup of tea. We all think the series is the best yet."
And there was plenty of drama last night as Fran held a family at gunpoint, chased teen hostage Kellie through a derelict Celtic Tiger estate and wrestled her to the ground.
But King Nidge has already started eyeing up other business ventures.
The world of blackmail, drills and dentist chairs seems a lot more appealing than kidnapping and holding families hostage on ghost estates.
Nidge spots Andrew; a client who has fallen behind on his tab at his local brothel.
Never one to miss a golden opportunity, Nidge realises a dental business is the perfect cover to import large quantities of drugs.
It's shaping up to be the perfect crime.
Last night, two new characters -- Tony Award winning Brian F O'Brian, who starred in Million Dollar Baby and teen actress Kelly Thorton, who played the part of Kellie (pictured inset) -- made their debuts on the show.
Speaking ahead of the last night's episode Thorton said she was excited to see how her friends would respond. "I'm really, really excited knowing all my friends are going to be watching it, I'm nervous how they'll respond."
There are plenty of other fresh faces appearing on screen.
Bewley's heiress and actress Kelly Campbell is another new ingenue.
This isn't the first time Kelly has got up, close and personal with Love/ Hate cast and crew -- she recently starred alongside Aidan Gillen, aka John Boy, in The Good Man.
"It was a joy to film," she said at the premiere early this year.
"It was lovely playing alongside such an intense actor like Aidan. He's very intelligent, very no nonsense.".
Last night, Twitter exploded with Love/Hate tweets as fans rushed to share their thoughts and opinions on the season premiere.
Susan Loughnane, who plays junkie Debbie, was travelling on a train to Liverpool and said she was devastated to miss newbie Brian F O'Byrne's first appearance on the show but was delighted the show got such a good reception.
New cop on the block Heffernan stayed in to avoid the madness and watched the episode with his family. "It was my dad's birthday last night so I stayed in and watched it with him. It was fairly low key.
"I didn't head out afterwards. I just let it sit and settle for a bit. And checked out the reaction to it.
"It's a great show to be part of and I'm really excited to watch the rest of the series. None of us get to see the rough cut so there's a bit of anticipation surrounding each episode."
