The only thing I think they missed out on was not showing more of Q's experience losing his powers. I've said it before, but having him pop in and out of scenes still gives the impression of power, which apparently he has little of left, so show its lack. Have him hailing a cab or working in a cafe on a laptop. How about going to a storage facility which would suggest he preplanned a lot of this because he was afraid of the darkened temporal horizon and needed contingency plans. Those are the kinds of things we needed to see, not Rios continuously flirting with some woman he's known for 2 days and we know barely anything about - and don't care either way. Hell, show more of Seven enjoying being fully human instead of just some one-off lines and a shot of her drinking at some gala with exposition from Raffi. I mean, hell, many of these things could have still been done with one or two actors if COVID was a concern, which obviously it was. But give us some damn character development. Or I guess, just have them run around serving the plots. Also, Picard's trauma over his mom's suicide I gotta say just hasn't been paced well and I'm still confused how it fits in with Q's claim he needed atonement and forgiveness. Maybe it's just the cliched idea that fear can hold you back and in this case it caused Picard to ruin chances of peace with the Borg, and in turn within himself. Blah. We get it.
