What amazes me about this episode
is how much character development
the writers packed into two hours. In this episode alone, we learn that:
The new Galaxy-class USS Enterprise (NCC-1701-D) is en route to Farpoint Station to learn how they were able to build such a great station so quickly on a planet with lots of geothermal energy but few other resources.
A mysterious energy field traps the Enterprise (we haven't seen that before, now have we?) and Q beams himself aboard dressed as a post-Renaissance explorer, possibly Christopher Columbus, with a wacky Amish raft of thee and thou-ery.
Q says that humans are a savage race, always have been, always will be. Picard suggests that Q judge humanity not on its past but on how it behaves now. Q is delighted by the suggestion and promises that the mystery of Farpoint Station will be a challenge that will demonstrate what humanity has become.
In the end, Q reluctantly agrees that humanity is better than it once was. He has taken to calling Picard "mon capitaine" ("my captain"), which I suppose counts as character development for omnipotent characters. Just before the credits roll, Picard promises that their future adventures won't be like this one -- they'll be much more interesting.
