So I have just recently watched the episode which I believe is titled 'The Q and The Grey', in which Janeway goes to the Q continuum. What I don't understand is how the show's writers could have possibly thought it a good idea to show the Q continuum on-screen. I understand it was shown the way it is because it is shown in a way a human such as Janeway could comprehend, but I find it much more reasonable from the perspective of the show to have done it so that the Q continuum is completely beyond human comprehension and as such cannot be shown on-screen. Or better yet, just leave Q in TNG.
