As Up moves into its primary storyline, that's the challenge co-writer/director Pete Docter (Monsters, Inc.) faces. In the present day, Carl (Edward Asner) is now a curmudgeonly septuagenarian, living alone in his house while high-rise development goes on around him. Facing the prospect of life in a retirement home, Carl instead sends a massive cascade of balloons through his chimney, launching the house into the air with a plan to head to a remote South American jungle There's also an unexpected hitchhiker: Russell (Jordan Nagai), a young Wilderness Explorer who didn't take the hint that Carl didn't want to be helped across the street.
Instead, the pleasures in Up emerge from the periphery, and there are plenty of them. Once they arrive at their destination, Carl and Russell discover a rare rainbow-hued bird that Russell dubs Kevin, and the animators have great fun with its playful expressiveness. Our heroes also run across the dogs outfitted by long-lost explorer Charles Muntz (Christopher Plummer) with voice-generating electronic collars, and the gimmick of verbalizing what we imagine is going on in a real canine's short-attention-span head is used to riotous effect-most notably in the character of the over-eager mutt Dug (voiced by Peterson). Unlike contemporary animated fare that tosses out pop-culture references at regular intervals, Up maintains a Pixar tradition of basing its humor on character-and even when an outside reference does sneak in, like dogs playing poker, it's understated enough to warrant a big laugh.
There's no question that Up delivers as entertainment, even when compared to other summer adventures. Docter directs a few tremendously satisfying action sequences, including a chase sequence across cliffs and rivers, an airborne dogfight that actually involves dogs, and what may be cinema's first knock-down drag-out hand-to-hand combat between two characters old enough to qualify for Social Security. It's energetic in providing material for Pixar's first 3-D release, and it's fun.
What it's not-at least not enough of the time-is truly transporting. That's a high standard for any film to live up to, and maybe it's an unfair one. Up certainly shows more storytelling prowess than most of what shows up on your neighborhood theater screen, and finds another touching moment near its conclusion. But nothing matches the magic of that early sequence, and Carl doesn't prove to be nearly as interesting or engaging a protagonist once he actually starts talking. Docter plays the best material he has at the outset, and as a result he faces the blessing/curse of being part of the Pixar legacy: He crafts an enjoyable, at times lovely piece of family-friendly filmmaking, and it still ends up feeling a bit disappointing.Up ★★★✩✩
