I wonder how much 3D has helped STID, I'd like to see 2D and IMAX only for the next movie as 3D did add to the budget and you wonder was it needed.
It has helped keep the dollar figure similar to st09
I think if it was just in 2D the $$$ would be 25-30% lower.
Less people seeing STID than ST09.
Converting a 2D movie to 3D costs more than filming in 3D to start with, so film in 3D next time with another director willing to do so.
