The first film is the only worthwhile entry in this British Christmas franchise, while the sequels Danger in the Manger! and Dude, Where's My Donkey?! were terrible, and, having read the negative reviews, my hopes were very low for the fourth film, directed by Debbie Isitt (Confetti). Basically, Jerry Poppy (Simon Lipkin), the long-lost brother of Desmond Poppy, has come looking for his brother at St. Bernadette's Catholic school in Coventry. But Desmond has already gone, having moved to Australia, so headteacher Mrs. Keen (Celia Imrie) allows Jerry to stay and become the new teaching assistant. Jerry is equally as childish, over-the-top, and enthusiastic about Christmas, music, and spending time with the children as his brother. Meanwhile, arriving in the United Kingdom from Syria is child refugee Doru (Brian Bartle), who has been separated from his father. He is currently being looked after by Nina (Meera Syal), but Jerry is determined to help him find his dad. Jerry meanwhile has nowhere to live, and he is thrown out after it doesn't work out staying with teacher Mr. Johnson (Daniel Boys). So, Jerry stays in the house of pupil Barnaby Hargreaves (Rupert Turnbull), who hides from Barnaby's parents, father Robert (Hugh Dennis) and mother Clara (Anna Chancellor). Jerry is highly excited about the chance to perform a rock opera, which will be overseen by successful theatre musical producer Emmanuel Cavendish (Craig Revel Horwood). In the end, Jerry and the children perform their rock opera version of the Nativity to a crowd on a public stage. In their musical, Miss Shelly (Helen George), Farmer Beatie (Ruth Jones), Angel Matthews (Jessica Hynes) and the Lord Mayor (Vincent Franklin) make appearances. Cavendish does threaten to spoil it, due to being rejected from the show, but he is allowed onstage. In the end, Doru is reunited with his father (Ramin Karimloo), and Jerry and the kids are delighted as the show is applauded by the crowd. Also starring Gabriel Vick as Hugo Alexander, and Trish Adudu as Reporter. Lipkin is perhaps an even more increased version of original star Marc Wooton, much more irritating, childish, and over-the-top, becoming almost creepy, the other well-known cast members are wasted, and the Strictly Come Dancing judge in his film debut is only mildly memorable essentially being himself. Like the three predecessors there are plenty of song and dance numbers, some good some naff, and the children are cute, but the script is terrible, the subplots in between the main plot are pointless and boring, and the jokes are dismal, this is easily the worst of the family film series so far, an awful seasonal comedy. Pretty poor!
