Im glad I only rented this. It does give you the option of watching in 2d or 3d. The blu ray 2d option is as expected but the 3d is terrible for home viewing. It was so bad at one point they had to throw a shovel full of dirt at the camera being the highlight. Im amazed IMAX would even identify with this feeble attempt at 3d. But while Im at it if you get the chance to view it and want a good 3d experience at home watch "Legends of flight" It is a documentary with 5 star 3d effects.
