The only problem I've ever had with this episode is the dialogue right after the cube's destruction, ending with:
Riker: "What do you remember?"
Period. End of scene. It says everything this dramatic two-parter needs, the verbal equivalent of the single tear.
But they went on to have Picard, still Borgified, add on: "Including some brilliantly unorthodox strategy from a former first officer of mine."
It completely ruins the dramatic import of the scene, IMO.
