Up's characters have all the charm of their movie counterparts – right down to the way they move. The graphics are top notch, though not exactly Pixar quality. In both foreground and background, the unlikely heroes, outrageous villains, and tropical environs look about as good as any movie-based animated game can for this generation of consoles. And while you can't explore everywhere you want to as you could in the WALL-E game, you don't really notice that you're on a path from which you can't really stray.
Up, while good, is not THQ's finest hour when it comes to its stable of Pixar-related games. Some of the attention to detail – which makes or breaks a game like this – is missing. Carl, the oldster, often whacks Russell with his cane when he is trying to crack open coconuts or smash bugs. Carl is not supposed to do that but the computer-controlled Russell gets too close to the cane, and - whack - he's down on his back. Also, when swimming through a supposedly harrowing cave filled with rapids and giant snakes, there's not much to do except collect coins. In fact, if you don't do anything, you still get to the end of the run unscathed. And sometimes, Russell's dialog is cut off by another line of dialog. That essential suspension of disbelief is occasionally missing and with it goes your willingness to be emotionally touched – which is sad because the movie itself is so appealing.
