I saw Let Me In, which is a remake of Let the Right One In this past weekend. It was very well shot. However you could tell a VFX shot was coming because the whole image looked affected before the VFX kicked in. The VFX shots looked like they were filmed on a digital camera shooting at 59.97 or a very high shutter rate. They lost all motion blur and looked super crisp. What is that and why does it happen? And how does one avoid it?
I would liken it to VFX shots back in the day when the effects were put on a second print and those shots just feel a bit different than the rest of the film.
