Up is really boring, and I was ready to fall asleep about 25% through it.
But Wall-E, I saw it in theaters, and I was so happy and excited to see it, because it looked really good and got great reviews.. but only about 15% of the movie had speaking.. and I'm not here for that, probably the biggest disappointment that was paid for, since I had high expectations.
Up & Wall-E are the only ones I hate, the rest of Pixar's movies are good. Hopefully they can keep up and make great one after those two messes though.
