Fantastic movie. Pixar is the saving grace for Disney's Animation studios, that's for sure. Wall-e was an emotional film, and I admit I cried towards the end... but I was crying throughout Up. Fantastic ride of emotions. The attention to detail rivals (if not bests) Walt Disney's top 9 animators...
if there was a flaw there were too many dumb dog jokes, but that's forgivable. You needed the levity in between the darker and more emotional storylines.
Was it farfetched in some ways, yes, but that made it even more fantastic.
Great 90 mins or so... totally worth seeing.
