New England Aquarium and Under the Sea in 3D on IMAX was pleasant enough. I can watch fish in aquariums for hours. And the IMAX movie was immersive (pun intended) without being 3D gimmicky. I groaned (inside, at least) at some of the narration, but was fascinated by some of the footage, particularly of cuttlefish changing color and convict fish feeding in a wave across the sandy floor.
