My memory of VGR is pretty vague, but I recall that there were some...and that ENT did at least one of them yet again.
Ok. I do know that ENT had an episode that was basically the same as an episode of DS9, where a group of aliens come to find out that they’re all actually holograms. And Rene Auberjonois was in it to boot!
voyager was actually done really well. It was episodic but it had its arcs and threads running through the show.
