Honestly? Not as bad as I was expecting it to be.
It was all but impossible to lift my expectations off the ground after they missed the mark on the post-Anduin cinematic as hard as they did. And my disappointment in that cinematic kind of stains my opinion on this one, with regards to Sylvanas, anyway.
But on its own, there's really nothing too bad that I can say about either of the cinematics. Tyrande was the correct person to defer judgment to. The punishment that Sylvanas was given, all things considered, wasn't a poor one. "Community service" it may be, but as was said when this epilogue began, the Shadowlands aren't suddenly fixed just because the Jailer is dead. This sort of service needs to be done, and just plain giving Sylvanas the death penalty or consigning her to an eternity of actual torture doesn't actually help to heal the Shadowlands. Forcing Sylvanas to clean up the mess she made is as fitting as it gets, and falls right in line with the tone of the whole epilogue.
They were solid cinematics, and in my opinion, a solid ending to this chapter of Sylvanas's story. I just wish that the rest of Shadowlands' story was as solid.
