Just took my kids to see this today. First off, let me start by saying it was just cool seeing this on the big screen with my kids. I knew going in the 3D wasn't going to pop. In fact, there's a YouTube interview of Lucas saying he didn't want things to pop out at you. But instead give you a sense of depth. And I have to say that pretty much sums it up (although the 3D doesn't really add anything either).
My disappointment, if you can call it that, is in the audio, or lack thereof. When I watched TPM in my HT on BD, you could literally feel it in your ribs when the lightsabers struck one another. Also, the pod race was foundation cracking awesomeness at home. In this release in the theater, the audio seemed anemic and weak.
Take life with a grain of salt... a slice of lime, and a shot of tequila
