Nice episode. Of course, I knew they weren't going to kill off Data for a third time and that his surrender was a trick. Still, beautifully done and a big TNG movie fix for me. It always seemed so dull and trite that Data could gain emotions from something as tawdry as an 'emotion chip'. Him being an amalgamation of Lore and himself makes so much more sense and feels so much more satisfying for the character.
Sad to see Vadic go. Shaw is still on his Hansen trip but I have a feeling he will acknowledge Seven properly by the end.
Other thoughts:
Nice to see 'Spot', although I know it's not the original Spot. I think there were about three original Spot's anyway.
Is that the Denise Crosby appearance we were teased with over and done?
The idea that Data is incapable of using contractions doesn't even tally with the evidence presented in TNG. He did it before Datalore and he did it after so it seems a bit stupid to bring it up.
Nice to see the Worf/Troi relationship acknowledged, even if just as undertones.
Good! Very good! I can't believe there are only two more.
