so, I`ve seen Dreamwork`s Monsters Vs Aliens movie in Imax cinema. It looked fantastic! I can imagine it wouldn`t be so good without the 3rd dimension. You just feel much closer to those guys almost like you can touch them and also feel the big scale of things. Especially with giant and small proportioned characters in this movie, it was really magical. It might all sound obvious as it`s IMAX afterall, but I`ve seen Beowulf in IMAX and it wasn`t as exciting being 3D as this one. Maybe because Monsters Vs Aliens is cartoony movie and it was more fun to feel standing next to giant foot of Susan or flying along with Insecto around huge alien spacecraft. Also it looks like people have learned a bit more about how to use this technology.
p.s. Pixar`s UP is supposed to be stereoscopic too, and actually first movie of this kind from Pixar, so let`s see in june (prem. is may 29)
