There were a lot of misses. I think the weakness was probably mostly from that Piller was, between
Deep Space Nine and
Voyager, mostly not involved, and Taylor was, aside from being I think not as strong a showrunner as Piller, also dividing her time with development of
Voyager. Braga, Menosky, Echevarria and yes Moore too had always been hit-or-miss but with that decreased supervision (as well as Braga and Moore also working on
Generations) they had more misses in their ratios in season 7.
In particular, Braga went too far with "Genesis" and Menosky with "Emergence" and "Masks" and with Echevarria's "Firstborn" it really felt like rehashing what we'd already seen before and "Bloodlines" a safe and generic take, going-through-the-motions of a Picard-having-a-son story. It seemed like the writers had become a lot less interested in the characters and kept them in place (a little the case in season 6 but a lot more in 7). But there were also some big gems, I think "Phantasms" and "Parallels" more for the sci-fi aspects and "Attached", "Dark Page", "Preemptive Strike", "The Pegasus" more for the characters, aside from the finale.
What I didn't like is cramming all the "family" episodes in there. Geordi's long-lost mother, Troi's long-lost sister, Data's long-lost mother, Worf's long-lost brother, Picard's long-lost "son." That all would've been fine if they'd spread it out over the course of a few seasons but all squeezed together in one season it became very noticeable as a writing weakness.
Troi's was not-mentioned for pretty good reason and Geordi's for an OK reason, Worf's for an OK reason (though that episode was awful, in part because I usually like Paul Sorvino), with Data that episode really felt like desperation, the whole episode a slow and unbelievable retcon.
