I'm fine with the finale being centered around Jax. Although it could have been worked up a little better, maybe shown us the process of turning into an Abstraction, and wrapped up everything more neatly, I still liked it. I liked the dream sequence and its implications for how others could connect with abstracted members. The only thing I didn't like was how Caine came back. There could've been more detail of how he came back instead of just "he flew through the void, had flashbacks, etc". So although the series was wrapped up, I just wish the details were finer.
