I second that. I've grown weary of the "it was all a dream" episodes (or sometimes, "it was all a holodeck simulation"), I'd have hated seeing that happening to a whole series. Yuck.
The only time I found a breaking of the fourth wall in Trek quite funny (not that there are many of them to begin with, though) was in the TNG Moriarty episode (Ship in a bottle IIRC), where Picard jokingly muses about the fact that they could be themselves an illusion appearing on a box in someone's house.
"The main difference between Trekkies and Manchester United fans is that Trekkies never trashed a train carriage. So why are the Trekkies the social outcasts?"
