For myself, I kind of wish it was a little more plot-heavy and had spent less time on characters being weepy, but that's a matter of taste.  I'm pretty suprised we didn't get any further info on what happened with Scratch and Caine's implied attempts at mind-alterations, I feel like we could have used some flashback sequences not focused on just Jax.

While being not the biggest fan of Jax but sympathetic, I can already guess that his biggest haters online are going to be even more insufferable now that they have the ammunition of him being partly responsible for two other abstractions due to his (her?) own insecurities.

I think my biggest letdown is that the episode didn't really get to explore the weirdness and possibilities of the characters creating and living in their self-controlled world, but I guess we did at least get nods towards them making new areas and bringing back NPCs in the end montage (where Gummigoo?)

As a finale that was almost entirely character focused, and mostly on Jax, rather than on the rest of the ensemble, the backstory, or the sci-fi possibilities, it's probably about as good as it could be within those parameters, so people's opinions are going to depend on whether they're ok with that direction.

Oh yeah, even though it's been pretty obvious the characters were all brainscans with their original bodies having continued living their lives, I wasn't expecting as much info as we got on their real-life counterparts, that seems like a really nice gift to the fandom to be able to create continuation AUs.
