While "Q" drives me crazy (because of his omnipotence stealing free will from the Enterprise), this episode is still quite startling. John Delancy's character shows up demanding to be made part of the crew. Picard can see nothing positive about this. He rejects the great one's offer and the next thing we know, the ship is sent 700 light years from there, into another quadrant that should not have been explored for years. Q continues to taunt the crew and Picard holds firm. It's probably that he sees the reality that if he relents, there is no purpose any more. The sad thing is that the Enterprise now meets the Borg, one of the most creative entities produced in fiction. They, of course, are a bee-like culture where there is a collective rather than individuals. They act in concert rather than alone. They are also a humorless juggernaut, beyond reason, whose sole purpose is to absorb other species and add this information to their collective. When attacked and damaged, they move quickly to repair and move on their insidious journey. Unfortunately, in the process of investigating this thing, a number of crew members are killed. Picard is largely responsible and must look inward to see if his ego was central to this loss of life. This is a pivotal episode, setting up an amazing series of encounters that will take place along the way.
