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.
Oh, I imagine that swing would be wild! I just started into Voyager again, but I went into it after finishing TNG. It’s not quite as bad that way. I normally take some breaks or at least space out episodes a bit more when watching those two.
