An excellent episode which is virtually certain to displace "Measure" as Trek's most venerated hour of space court.
One thing that always strikes me about SNW—even the middling episodes—is just how vivid, bright, and beautiful this show is. Grimdark has its moments, but this visual style is a much better and more natural fit for Star Trek.
Canon Trek is rife with contradictions. The rest of your comment is a healthy approach to thinking about canon, though.
