I took my 10 year old son to see this today, in 3D it was soooo fun, and such a laugh, listening to all the little kids giggle at stuff was delightful.
The 3D added to the experience, and gave the impression that we where flying along with the house. The depth and colour was very good.
The story line was easy to follow and a little sad in places, but with an uplifting ending. I definitely know what we will be humming next time my dad comes down stairs on his stair lift hehe.

A great way to spend a couple of hours with your kids, well worth the money.
