The first instalment of the new RTÉ crime drama Kin aired on Sunday night and viewers were impressed by the "tense" and "slick" episode.

The eight-part crime saga starring Aidan Gillen, Clare Dunne, Ciarán Hinds and Maria Doyle Kennedy, sees Dublin crime family the Kinsellas go to war after a member of their clan is killed.

Warning: Spoiler alert!

In the series opener, Eric (Sam Keeley), the son of family patriarch Frank Kinsella (Aidan Gillen), got himself into trouble when he decided to mess with the Cunningham family, the ruling crime syndicate under which the Kinsellas operate.

After Eric carried out a drive-by shooting, the Cunninghams retaliated by attacking him while he was at the gym and Jamie, Amanda (Clare Dunne) and Jimmy Kinsella's (Emmet J Scanlan) son, was shot and killed in the crossfire.

Viewers praised the shocking and tense first episode on Twitter.

They also singled out praise for English actor Charlie Cox, who plays Michael Kinsella, and his excellent Irish accent, with some comparing it to Daisy Edgar Jones' command of the Irish accent in Normal People.

Here's a sneak peek of what's coming up in episode two.

And here's a little reminder of the Kinsella family tree if you need a refresher ahead of next week's instalment.

Kin airs on RTÉ One, Sunday nights at 9.30pm with catch-up on RTÉ Player.
