I came across this box set and it's really messing me up for a lot of reasons (it is marked TOS despite having characters from all over the place, and for some mistaken reason Gul Dukat is included) but what I really wanted to talk about was Q's inclusion.
Do people usually consider him a villain?
I suppose he has done a lot of things that would be considered antagonistic, with a big one getting a number of Enterprise crew members killed in the first encounter with the Borg, but that seems, at least from his point of view a tough love moment. In the long term, Q did seem to have the survival of humanity as a goal. His judgment of humans was pompous but not villainous.
In the episode where he wore that outfit he held the Enterprise hostage, froze two crew members, and threatened to wipe out humanity.
