I've been faithfully watching every single Disney/Pixar movie year after year, and they've never failed me, not even Cars (even though that one was pretty retarded).

Up was one of the most touching movies I've ever watched. It was extremely sweet and moving, and the characters were genuine, real and engaging - everything was brilliantly executed as usual.

Now my favourite Pixar movies rank in this order:

1) Wall-E
2) The Incredibles
3) Finding Nemo
4) Up

5) And all the rest go down here

Watch it if you can - it's good enough to make you cry.
