The line that struck me about the most recent review:
He doesn't know the truth!We could get an explanation for [Odo's origins] later (I actually suspect we will, and it probably has something to do with those pesky wormhole aliens)Pretty much all the first-timers on this site know about the Changelings and many of the other major plot events through osmosis, but this guy doesn't. Here's hoping he remains unspoiled about these things.
Here's hoping he never reads the comments.
