I don’t remember crying at the beginning of Up. I can remember the opening sequence relatively vividly, but the rest of the movie is a blur. I remember Doug the talking dog. The balloons. A colorful bird? An airship? Some other dogs? While the opening sequence of Up is beautiful, even a recognizable masterpiece, the movie on the whole is of lower Pixar quality (which is still quite good).
Inside Out is a masterpiece all the way through. I was sitting in the middle of the theater, surrounded by families, kids, even teens on dates. And there I was, sobbing, tears streaming down my face, snot coming down my nose, and the full catharsis of the movie totally rocking me. The beginning of Up might be sadder, but Inside Out made that sadness okay.
