Nanny McPhee/YMMV

Adaptation Displacement: The movie was adapted from a series of books called Nurse Matilda, with several changes.
Complete Monster: Uncle Phil in the sequel. You could feel for him a little bit when he was trying to convince his sister in law to sell the farm to save his hide from loan sharks, but to fake your own brother's death? And do so to his children's faces?. There's not much that could redeem a man after that.
Non Sequitur Scene: In the sequel, the uncle lets all the farm's piglets out of their pen and the children have to hunt them down, and Nanny McPhee decides that dragging out this task further will teach them a lesson in teamwork. Which justifies making the pigs harder to catch by granting them some speed and agility, but seriously... synchronized swimming?
Crowning Moment of Funny: "Pleased to meet you. I'm Oglington Fartworthy."
- From the sequel: the city and country girls have to work together to prevent Isabel from signing the farm over to the uncle without letting on that the Disappeared Dad may be alive before proof is in hand. It's not the Bavarian Fire Drill that follows (with the city girl going Eek! A Mouse! like crazy), it's the city girl trying to instruct the country girl's next move while still screaming .
Crowning Moment of Heartwarming: When the father comes back from being MIA in the second movie.
Even Better Sequel: Nanny McPhee Returns, according to reviewers.
Fridge Logic: In the sequel, the two boys headed to the War office in the capital to ensure they had proof that the Disappeared Dad was still alive... yet they hear the news and immediately leave emptyhanded? At least grab the paper ribbon code thingy from the radio guy first...
Moral Event Horizon: In the sequel Phil's forging of the telegram.
Nightmare Fuel: Baby in the stew. Th-the baby. The baby...sure, she didn't actually go in the stew, but the chicken boiling up and gah...
- Probably rates a What the Hell, Hero?, considering the sister will have to remember how she was almost forced to boil a baby alive.
- The wriggly black goo Nanny McPhee gives to the children as 'measle medicine'.
- Miss Topsey and Miss Turvey and their threats about what they're going to do to Phil in the sequel film. It's even worse in both the original British version and in the novelization.
  - I mean, showing up in nurses outfits, planning on scooping out a man's insides out while he was handcuffed with no escape while he was still alive...then stuffing him and sticking his dead body on a spike as a warning to everyone else? And actually brandishing a huge scooping spoon thing at one point.? That doesn't sound like a kid's movie to me. I mean...I thought I'd see that in Saw.
  - The first film had minor examples of mood whiplash, with the Aunt wanting to take one of the girls away, and the Miss Topsy and Miss Turvy in the sequel was major mood whiplash. If a third film is made, I wonder what the mood whiplash will be like?
