In my opinion, it is pure and simply the worst movie made by Pixar so far (though I'm not a huge fan of 'A Bug's Life' either) and that's why it is rather dubious that they decided to make a sequel for this. Eventually, even though this sequel was even more poorly received, I enjoyed it slightly more than this first installment and, apparently, Disney/Pixar decided that they wouldn't stop here and produced the spin-off 'Planes'. Anyway, even though I didn't like much this movie (if I'm not mistaken, it is actually the only Pixar feature that I haven't seen in the theater), it doesn't mean it was actually bad whatsoever. Indeed, Pixar hasn't made a real stinker yet (though it has been a while since they have done something truly amazing). In this case, the animation was still really gorgeous and the whole thing was still mildly entertaining. The point is that, this time, it was clearly aimed towards very young children and the rest of us didn't really care about the whole thing. Still, it has more charm and wit than many other animated features you can find on the market nowadays and it is definitely worth a look, especially if you like the genre.
