Don't hesitate to get it. Lots of 3D, especially in the beginning. This is definitely a Tier 0 title. My wife and I really didn't want to watch it, but the kids did. I'm glad we caved in.
My copy came yesterday. I ordered Happy Feet and The Matrix Ultimate Collection from Warner Home Video. I cancelled my Amazon order for The Matrix. I ended up getting both at Warner for $12 more.
