This episode ultimaty takes the viewer to the centre of the galaxy. Is there something ST script writers understand that no one else does ? Because at our galaxy's centre, the Enterprise finds surprisingly little. A hologram of a giant head appears on the flagship's bridge. Which is impressive. But that's it. In general, STTNG script writers' imagination is unmatched. In other episodes, we saw living space ships, robotic Borg, time travellers. Other SciFi books attribute the weirdest worlds to our galaxy's centre. Enough to spawn another seperate Star Trek show. The writers of this episide didn't get overly excited. At least not about that particular region. Which made me wonder whether our galaxy's centre really isn't very interesting.
