The idea of a panda doing kung fu seems so natural and just... works. This was an excellent animation where there was a lot of humour, action and a solid story. The animation was great for it's time (it seems a bit too plasticky now, there's a sheen and defined edges that it can seem odd). It never got boring, every scene was worthwhile. It's engaging too as you know the showdown between Po and Tai Long was forthcoming and you wanted to see how Po could elevate in his kung fu mastery to be able to defeat Tai Long. Along the way, you get numerous fight scenes which was a joy to watch. The humour worked really well here, there were more than a few places where it was hilarious. It did sometimes rely on some kiddy humour (Po squishing on Tai Long, mild toilet humour etc) which wasn't as good (you have to take into account the intended audience though, so it is forgiveable). The climax of the film didn't disappoint and I liked how it wrapped a lot of ideas that were foreshadowed earlier. This meant that the way Po won makes sense and you didn't feel cheated.
