Wait, never mind, it's a 3D (pfffhahaha) IMAX version of the half-hour all-star-cast film, originally released in the same year as this one.
They should just not bother to 3D-ify the 2D sequences. Return to the days of 'put on your 3D glasses now'. Maybe even have pointless clear or lensless 2D glasses for people to wear during the 2D sequences.
