Although not in 3D, because apparently the only local theatre doesn't do 3D. Ah well.
I really liked it. It was suprisingly mature (or not-so-suprisingly, considering this is Pixar). I mean, the prolouge was just...
first of all, the part where Carl is watching the reel about Muntz not only leads to Carl's interest in adventure and his meeting Ellie, but also perfectly sets up the villian. Not just said villian's existance and his motivation, but the fact that he really, really likes dogs. The idea that this guy would make translator collars for his dogs is allot more plausible when we know that he designed the interior of his zeplin specifically to keep his dogs happy, fit, and comfortable.
And after Carl marries Ellie, the way that the conveyed so much (how life kept getting in the way of their dream, how Ellie wanted to have children but had a miscariage, Ellie) without dialouge. They've already done this sort of thing in their shorts and in WALL-E, but in an age where movies tend to be heavy on dialouge, Pixar's ability to show without telling will never stop amazing me.
And the balloons! In the real world a single helium balloon can't lift one stick, a dozon balloons can't lift a vender's cart, and a house can't be lifted by thousands of balloons. But the scenes at the begining, where a balloon can carry a stick and a balloon cart is in danger of floating away, the rules of the universe are established, and the basic premise of the movie itself becomes less implausible in light of that.
And the designs were lovely. I love how all the characters are so distictively shaped, especially Carl with his boxxy features. Kevin was very convincingly avian; everything about his design and movement screamed "bird!" in a way that most cartoon birds don't (mainly because most cartoon birds have to be relatable to their mamalian audience). The rainforest was much more believable than the one in The Incredibles, though that's likely in part due to Up's setting being more heavily inspired by an actual place, while Nomanisan is basically a generic tropical island.
Also? The justification and execution of the talking dogs. Considering that most talking cartoon animals can talk without any explanation (how exactly would a dog pronounce sounds like PUH and VUH, I'd like to know) and act like fuzzy humans while doing so, it's nice to see a different take on the cartoon cliche.*
*(Not that I don't like any movies that do that. I love alot of the disney movies centering around talking animal characters. It's just that that particular teatment of the concept is so overused that it gets a little tiring after a while. Who wants to eat chocolate pies for the rest of their life?)
