There is no need to watch the whole thing, though of course you may if you wish. I has watched it carefully and I has not found any sexy or bad language in it. So it is not too bad an influence on young minds.
Though of course I must warn you that when Bert and Mary and the Banks children are on the roofs they is covered in soot. Note that this is not a very goodly way to keep oneself, a good living person keeps oneself clean on the inside and out.
However, the important part to watch is the bit when Mary and Bert go on a "Jolly Holiday" inside the chalk painting, on a holiday in the painting. Then they dance their ways to a nice little tea house and outs come ...
YES!
You has got it. Penguins.
Little penguins who is happy to act as waiters, because penguins are thoughtful types, and "at your service" is their way of thinking.
What is more, to demonstrate their cheerfulness and gladsomeness, they do a dance, and what is better, Bert joins in.
He demonstrates to human beings that Penguin Dancing is not beyond us, if we give it a go.
Now I would not say Bert is the most elegant dancer I has ever seen, but at least he give it a go, and he try to penguin dance.
That is something we should all aspire to. Give Penguin dancing a go, like Bert!
