I was letting my 3 yo cousin be in charge of the Netflix choices one evening and she was pulled, as if by some magnetic force, to "Barbie: LITDH". Believe you me; I tried everything in my power to get her to make another choice, but I eventually gave in and was very happy I did.
This show is very clever, they\ characters live their lives as dolls and it is hilarious to see them build their new sports cars fresh from the box and bake treats by jamming random ingredients into their toy oven. Barbie's house is so ridiculously over-the-top, it really is the 'Dream House' I would have created in my childhood. It is silly and playful, the characters are distinct and interesting (especially Ken, hubba hubba...).
Some people don't like the portrayal of Barbie on this show. I'll say this much: Barbie is perfection. She has everything you could possibly dream of, and yet she remains humble and generous throughout the series. The Barbie brand was always a form of escapism for me; I wouldn't expect her to be living through some real-world struggle, that's simply ridiculous.
Give this show a chance. Even if you're not a fan of Barbie movies, you might be pleasantly surprised!
