A lot of people claim this is peak Trek. However I disagree. It's certainly a fun episode though. I really enjoyed Q and his interactions with Picard and Guinan especially. Also, his motivations foreshadow the terror that will be wrought by the Borg in the future.
However, the ending is really bad. The fact that Q puts the Enterprise in a position of danger that ends in the deaths of 18 of its crew is terrifying. However, the way Picard reacts to those 18 deaths, is borderline sociopathic. He calmly forgives Q, and says that perhaps, he meant well. No matter the fact that he just basically put the enterprise in danger that led to many bad decisions, which resulted in those 18 deaths.
