Got this from Amazon and watched it with my brother yesterday on my PN63C8000 plasma; the results were mixed.
Overall a nice, sharp and colorful image with some good 3D moments of various dinosaurs seeming to poke their massive heads out of the screen; some of these closeups were almost disturbingly realistic.
Unfortunately there was also a lot of visible ghosting on this title; pretty much every scene which featured some area with shadows (and there were a lot of them, both live and CG) displayed a visible double image within the shaded section. The opening sequence in outer space with an asteroid hurtling towards Earth also had some pretty bad ghosting.
The disc also came with a bunch of previews of other Imax titles; sadly they were all in 2D.
For a budget title ($15.99 from Amazon) I still thought it was a good deal, but I was really disappointed at the apparently shoddy 3D mastering job that much of the title appeared to receive, especially considering the number of 3D titles that have now been released.
