I was turned off in this episode by the Voyager crew's initial reaction to Q. I felt like the show was trying to duplicate the Enterprise-Q relationship from The Next Generation, but without the history. Q put the Enterprise crew through hell, and that forever affected their relationship with him (especially Jean-Luc), but by the end there was a slowly developed lessoning of the animosity.
Captain Janeway acted like Picard in the middle of The Next Generation without any personal experience. Yes, they had heard about Q's interactions with the Enterprise, but they of course would only have had the facts. They wouldn't have the emotional connection.
I would have preferred to see the Voyager crew react with more of a sense of awe and wonder, with of course a bit of fear. Captain Janeway's first thought at encountering a Q should have been "Maybe he can help us get home". After all, they were seeking out the female Caretaker to help them get home - why should they view another being with the same power as a pure adversary to avoid?
Other than that I found the episode interesting. I was disappointed that Quinn didn't want to live, but I understand Hux's point about him just wanting his death for too long that he had no patience. I don't believe that he had personal experience as life as a mortal. I am disappointed with the character in-universe, not with the writing staff for that. It would have been very interesting to have a mortal Q as a crewmember, I would have enjoyed that much more than Seven of Nine. It might have been interesting to see him, now that he is facing the certainty of his own mortality, to feel some sense of fear over time.
