Saw this yesterday with the young 'un, and like everyone else here we absolutely loved it. Fantastic film, and it all makes a stunning trilogy. I hope they don't add a fourth, but I suppose at least with Pixar there'd be a guarantee of quality.
We saw it in 3D, and it's my first proper 3D film. I really enjoyed it, but to me the 3D effect was neither here nor there. I suppose it's a nice gimmick to draw crowRAB, but it didn't make any difference to the film. I didn't even notice it half the time. I'll be more impressed when they can do it without the glasses. They're a pain.
We also found the furnace scene a bit scary too. I really feared the worst! I can imagine the very young finding it a bit much. It was quite apocalyptic and intense.
