The kid who plays Jean Luc Picard is quite good - focused, carries scenes, a true actor .. loses
himself in the role.  The other kids are, well, kid actors.  Barely adequate, with the exception of
the girl who plays Ro.  She's quite good.  Being able to carry a scene is important.

The other two .. not so much.  The girl who plays Keiko does the scene acceptably with Miles
O'Brien, but she doesn't have the presence of, say, the actor who plays the young Picard.

What's weird about this episode is how quickly the other characters "get uncomfortable" with the 
kid characters, how they treat them as strangers.  Shouldn't they still recognize them?  Granted, these
are other actors in their place, but the characters should be recognizing them as younger versions
of themselves, not as different people.  Still, we are kind of "trapped" in the fact that these are
other actors, and on one level it makes sense for the other characters to be reacting to them as
such.  It conveys the weird meta- suspension of disbelief that is required to accept these actors
as who they are - characters that represent the younger versions of themselves.


The cool thing about the kid who plays Picard, is that he exudes command -
he puts out a command vibe.  Effortlessly.  Very good casting.  And acting.

When it's so hard to cast children, they really lucked out with this one.
And Ro.
