Any time the Star Trek shows used words and phrases like 'singularities' and 'quantum displacements' I usually hated the show--and "Visionary" is no exception. These sort of shows make for very slow programs--and ones that usually are stuck aboard the station or a ship.
When the episode begins, Chief O'Brien sees something weird...himself! Yes, he's standing on one side of the station and sees himself talking to Quark on the other. And, what follows is one instance after another where O'Brien is briefly transported five hours into the future. While it's never even considered that some intelligence might just be causing this, it sure seems reasonable. Instead, they all come up with some Trek-o-babble that explains everything and it all ends happily ever after.
As I said already, I don't like shows like this. I'd much rather have the crew DOING things and this one felt a bit boring.
Oh, and by the way, early in the show the Commander says that he wasn't aware that there were any Klingons on the station. Yet he doesn't seem to remember that there IS a Klingon restaurant there with a Klingon chef.
