As described at length above, the 3D sensation is nearly flawless, save for several instances of "ghosting," noted at the 18:30 mark as W.R. Monger flies around the compound on his jet pack; on the alien robot at 37:55; on a floating spoon at 47:38; and in several other shots throughout. Again, it cannot be stressed enough that such instances are the exception rather than the rule; the vast majority of the image is as smooth and distortion-free as one can imagine. Though the original 2D release of Monsters vs. Aliens was not available in anaglyph 3D, the companion short film, B.O.B.'s Big Break was; comparing the two one after another, there's simply no doubt as to how vastly superior full HD 3D Blu-ray is next to anaglyph, even with the few hiccups incurred through the course of the film and, to a lesser extent, B.O.B.'s Big Break. It's really like a transition from watching a worn VHS tape to a top-rated Blu-ray disc.
