It's a bit like Bosco meets Stranger Things as RTÉ One broadcasts a brand-new four-part mini-series for the whole family - and mixes the nostalgic with the surreal.Set in Lough Dan in Wicklow, where the Kelly clan decamp to for a reluctant family Holiday.

In fact, before long, things get really weird.
