How many folks have you met on holiday and promised to go and visit when you all get back home? Well for me that is always a bit like ouzo or metaxa - best enjoyed in situ but never a good idea when the trip wis actually over. The "Dalton" family are a bit down in the dumps. "Ben" (Scoot McNairy) has just relocated to London from the USA to find his job evaporated, wife "Louise" (Mackenzie Davis) is trying to keep things positive and their over-indulged daughter "Aggie" (Alix West Lefler) is an eleven year old joined (annoyingly) at the hip with her cuddly rabbit. They decide that they ought to take up the offer of spending a week with their new-found holiday friends and so head to the remote home of the ebullient "Paddy" (James McAvoy) and his family "Ciara" (Aisling Franciosi) and mute son "Ant" (Dan Hough). Initially it's all good fun - even if the sleeping arrangements leave something to be desired, but gradually it becomes clear that all is not as it might be amidst this idyllic setting. When young "Ant" manages to convey a menacing secret to "Aggie" then a distinct panic sets in amongst the visitors who conclude that a midnight flit is in order. Of course, it's not going to be that easy and adaptability and ingenuity become the family's buzzwords as things become a great deal more dangerous. It does come alive a bit for the last twenty minutes, even though these are all just a little far-fetched, but the rest of this is really little more than a showcase for McAvoy to shine. To be fair, he does turn in a decent enough effort eventually but we spend far too much time building to that denouement. The preamble, some on their holiday and most at their rustic residence all advances the storyline too slowly and meanderingly to sustain enough interest to carry it's almost two hour duration, and personally, I found the likelihood that these people would ever have become friends in the first place about as remote as his house. It's all watchable enough, but nothing very memorable I'm afraid.
