Eight Below was a great little film. Geared for the family audience to be sure, it was very enjoyable.
When an injury forces a Antarctic exploration team to leave basecamp to get to a hospital, they must leave their sled dogs behind to survive on their own. Months will pass before a resuce is even possible.
Keep in mind when you see this with kids that, yes, this movie is sad in a few places, and that there is one scene in particular that was scary enough to make every kid in the theater cry and all of the adults jump at once.
But I still have to recommend this film, it was good. And my 7 year old niece loved it.
