'Nanny McPhee' is really an ugly version of 'Mary Poppins' (Emma Thompson is even in the upcoming movie 'Saving Mr Banks') and far from being a masterpiece, even though the cast is pretty good (Emma Thompson, Colin Firth, Kelly MacDonald, Angela Lansbury, Celia Imrie, Imelda Staunton, Thomas Sangster), most of the acting isn't very good, Angela Lansbury and Imelda Staunton are over the top, Kelly MacDonald, Eliza Bennett, Samuel Honywood and Holly Gibbs don't give a crap and Colin Firth is in the wrong movie - his performance is overally depressed

Honestly, my brother wants to watch this all the time and I must've seen it at least 100 times by now, I wish he'd pick a much better movie as this one is just so tedious (so is 'Nim's Island' which he always chooses as well)
To conclude I think it is only really worth a look if you have young children, but even then there are many better movies you can watch.ย
