Pudsey the cheeky London stray dog is quite happy being a lone ranger, looking out for number one, until he meets siblings Molly, George and Tommy. After losing their father, their mother Gail is moving the family to the sleepy village of Chuffington and Pudsey tags along, to the dismay of their landlord, Mr. Thorne, and his cat Faustus. As Pudsey starts to settle in with the family and realises what he was missing when he was alone, he stumbles across Thorne's evil plan, and he determines to save them and the whole village.
Even for films aimed at kids, this is dreadful. Family moves to the country, acquiring the dog of the title on the way, even though dogs are not allowed in the countryside(!). The dog's thoughts are spoken by Walliams. The comedy is unremittingly leaden and the script bland. The dumb dog has only two tricks, repeated endlessly here. Hynes has named this as her one regret in her professional life. Pudsey won Britain's Got Talent in 2012 but doesn't exhibit much here.
