Synopsis: By tying thousands of balloon to his home, 78-year-old Carl Fredricksen sets out to fulfill his lifelong dream to see the wilds of South America. Right after lifting off, however, he learns he isn't alone on his journey, since Russell, a wilderness explorer 70 years his junior, has inadvertently become a stowaway on the trip.
Our Review: Hands down, Up will be one of the best films released in 2009. It's poignant, and goofy and gorgeous. The story and characters shine - you really care about what happens in this slightly outlandish fantasy, since the dialogue is more than just a few pop-culture references strung together to pass as humor, and the two main protaganists are well developed. The movie has some wonderful themes, such as loyalty and devotion and a determination to do what is right no matter the cost, that will resonate with children and adults alike. And if the 10-minute montage at the beginning doesn't make you tear up, then I'm not sure anything will! (Although you'll probably be smiling at the same time.)
While there is no real objectionable material, Up is rated PG rather than G. If you have very small, sensitive children they may be a little concerned about the fate of some of the animals in the movie or a few of the action scenes, but most should be fine. There are some great discussion points of which to take advantage with your family, as well.
