Agreed...even if the conversions are improving and looking better, I still can't watch them simply knowing that they are a conversion because in the back of my mind I know that a converted scene will NEVER completely replace a natively shot scene. You cannot replicate every single pixel, every single correct angle or reflection of every single object....it is purely guesswork and an artist's interpretation. Just shoot the film in native already and use a professional stereographer. Jeez...the industry usually makes millions from these films after all so its not as if they don't get rewarded for their efforts.
I have no problem with conversions for older films if done properly. After all, I converted Carnival of Souls and 12 mins from House on Haunted Hill to 3D and so to say anything else would be hypocritical.
