I have no idea why it is rated so poorly. My whole family was glued to the TV. It was very emotionally moving. Yes, some of the acting may be a bit sub-par, but what an inspiring, invigorating tale. If you've got children, they will love it.
And it's not Just For Children. I'm in my 40's and love films including Pulp Fiction and Fargo, but I was totally engrossed by this tale of seven children who refused to give up on their father's dreams. Near the end, I was close to tears as the story got more and more dramatic.
What makes this story so compelling is that it's based on fact. It's great to have a beautiful story that doesn't rely on huge budgets, phony story lines, expensive technology, and computer graphics. This is old fashioned movie making: based on a good story! Be sure to see if you enjoy wholesome, family oriented, adventure.
