This is the most complete of all the Trek collections, as it has ALL episodes from all three (TNG, DS9, & Voyager) series in which John de Lancie's character appeared. Since his first appearance in TNG's premiere episode "Encounter at Farpoint," de Lancie's delightful performances made Q an intriguing character who would appear numerous times more on TNG and even once on DS9. Sadly, his three appearances on Voyager, like those of the Borg, lessened the character's appeal. Still, the good outweighs the bad here.
I would recommend this to a friend
