Just saw the trailer and I really laughed! That's a good sign! I can't wait to see it; will be dragging my little (aged 17 and 2 months ) brother to see it as TS was his "thing" when he was little.
It looks like it'll be amazing. I'm far more worried about Cars 2 than Toy Story 3, but even then Pixar haven't put a foot wrong so far.
Amazing to think that Toy Story 2 started off as a completely commerical straight-to-DVD idea by Disney and yet Lassiter and the Pixar team still managed to turn it around into a brilliant film.
