I watched it for the first time the other week at a proper IMAX cinema.

It was very impressive, but I'm interested to know whether there's a big difference between it and normal cinemas. So much so that I'm thinking of going to watch it at the pictures on my lonesome.

I think the most impressive thing was how large the screen was. You had to move your head to see everything. I can't imagine that on normal ones.

But is that it? Is the 3D any better or not?

Moreover - how do you think they'll release it on DVD?
