What immediately bugs you when watching an episode? Mine is when they transport someone sitting down and they reintegrate in a standing position (or vice versa). Sure, the tech is near magical but my suspension of disbelief pretty much snaps when they do this.
So the episode with scotty in the next generation he invented a way for the pattern to not degrade. Its supposed to be relatively short term and have only so much capacity. Even during transport when their are issues it suggest they can lose the buffer. Im relatively accepting of it on that point.
