When Icheb dies in the first few minutes you know you're in for a wild episode! Too bad for his crazy actor (who didn't even get to play him.) Good continuity with Voyager when it was mentioned that he has no cortical node. He donated it to Seven at the start of season 7.
Jeri Ryan was great as Seven. She had some lines which sounded kind of "wrong" for Seven at first, except it's been over twenty years in the timeline since we last saw her so of course she's going to have changed. She still did subtle Seven face mannerisms. That last scene with Picard was really good. And leaving her as a killer sets up an arc for future appearances (I'm sure she'll be in the finale at least since she gave Picard her space phone number.)
So Seven and Vajazzle were pretty obviously lovers, right? Sorry Chakotay!
Quark being mentioned was CLEARLY to foreshadow the Ezri Dax appearance coming later.
Picard's fake French accent was really silly but kind of brilliant.
Raffi was better because she got to be competent and do stuff other than drink and moan about JL.
No pointless Cube scenes = good.
I was thinking Agnes was being mind controlled by Oh, but it really seemed like she killed Maddox (another recasting! I guess the original just teaches rathern than acts now) by choice.
