I saw Star Trek into Darkness the other day (very good film btw and well worth seeing) and while I was watching it was thinking did the fact it was shown in 3D really add that much to the overall experience? To be honest, sometimes the 3D effects become distracting and seem to have been placed there just to showcase the technology.
I also had the same impression when I saw The Hobbit, first in VF in 3D and then in VO in 2D. I have to say the 2D version was, in my subjective opinion, much better. I was just wondering if it was just me who thought this and I'm now massively showing my age!
