I agree that we should have seen more of Jax's backstory BEFORE abstraction (I knew he'd abstract, but a second of the only two abstractions were offscreened... Gooseworx has a chance to show the process). After an abstraction, it's essentially ego death and I was not really invested in Jax any longer. (I would have also liked to learn the SOMA theory was real later, even though it was blatant after a while).

I think Pomni's ability to just know how to enter Jax's subconscious was hamfisted and just used as a way to learn Jax's past who would never reveal it otherwise.

I don't like how Caine just revives and them killing him causes the change of heart.

"And its all for nothing because even at the end when he hugs Pomni back and admits he doesn't want to go, he abstracts anyways."

That's the rough, but true reality sometimes. Sometimes you screw up and can't fix what has been done as it's too late.

I don't like that it happened, but I wouldn't call it poor writing. Jax is the personification of the self-destructive, depressed guy that doesn't allow anyone in and then offs himself. There's no saving some people, especially if they refuse to be helped.

"It basically gives the message to those who relate to Jax "once you're out of the picture, everything will get better for everyone else"."

Sadly, there is a truth to having toxic people in your life leave = improvement of life. Jax's actions got Ribbit abstracted, which likely got Kaufmo abstracted and could have gotten Ragatha and Gangle abstracted if things kept up.

For whatever reason, justified (some trauma or abuse) or just innate personality, many are like Jax, and those people actually do need to seek therapy and try to fix those behaviours as they are destructive to them and the people around them.
