So Lindsay and I saw Up last night and I have to say that it pulled on my heart strings with the force of a thousand Iron Giants. I have to say that I am starting to dig this digital 3D stuff and Pixar really did a nice job with it. Monsters VS Aliens was fun but it was a little gimmicky at times; but given their 50 cult film inspiration it was totally forgivable. The use of the 3D in Up was very subtle for the most part and it was used more for providing a sense of depth and spacial volume then thoes "pow, in yo face" moments. This should help the film's enjoyment on DVD without the feeling of "is something is missing?".
So yeah, go see it in theaters. It was a real treat for the eyes and brain. Maybe if Wolverine was in 3D and had talking dogs... one can only dream.
