Most sequels suck.
If they're gonna ruin this masterpiece with a floppy comeback they better think twice before touching it.
Not Pixar's. There's only one film Pixar has made a sequel to, and that's Toy Story. Toy Story 2 > Toy Story, if you want my opinion. Pixar and Disney don't screw around with sequels. They always try to make them as good, if not better. Toy Story 3 will most likely be just as amazing as the first two. This one should be great as well. The only one I'm worried about is Cars 2. But, I trust Disney/Pixar to bring that film justice.
As much as I love Monsters Inc, Pixar needs to come out with originals again. Toy Story 3 is coming out this year, next years is Cars 2, so if they do Monsters Inc. 2, they'd be doing 3 sequels in a row.
Having said that, I would love to see MIke and Sully return.
No, Toy Story 3 comes out this summer, Cars 2 next summer, and The Bear and the Bow comes out winter of 2011, which makes 2011 special with 2 Disney/Pixars in one year! Then Newt comes out in 2012, and this probably 2013.
Most sequels suck.
But they should do a GREAT sequel
