i, personally, had no problem with the tractor-tipping scene. it was somewhat funny and if all the younger kids loved it, that's wonderful. i loved the end scene like everyone else and i loved the other Pixar films being turned into cars.
i also loved "one man band" it was cute and creative. Ratoutille also looks fun, much unlike the other CGI trailers i saw.
the theater i went to also was very full considering that the movie had been out for about 2 weeks by then. and everyone in the theater seemed to enjoy the movie. it was not only families (which i don't even see as a bad thing in the first place) and everyone was laughing throughout the whole thing.
i loved the scene during the Piston Cup where the women are "bumper-to-bumper" in line for the restroom and the men are in-and-out. that was cute and so true to real-life. (i'm sure all of us girls know how long those lines can be
btw, my brother and i loved guido, filmore, and of course mater (hearing all the younger kids in the theater recite "the name's mater like ta-mater, but without the ta" was cute).
however, one thing i did not like about the movie was the lack of memorable songs like those of past Pixar movies. maybe that could be due to my own ignorance but i think songs like "life is a highway", "real gone", and a remake of "route 66" should be the only major songs played. although i did like them, i don't think that they should be the only ones. but again, my thoughts in this sectiopn could be due to my own ignorance
