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.
In Strange New Worlds, which is set earlier than Scotty could have invented that, the doctor keeps patients in the pattern buffer when their condition is deteriorating and there’s nothing he can do to stop it. It’s presented as janky and his own invention, and not necessarily harmless.
