Looking back I agree there were other weak aspects of Psycho Pass (and I said before it had weak world building).
I think Psycho Pass peaked at the Kagari episode. That was the strongest episode of the series for me.
Although there were scenes after that I highly enjoyed: the discussion between Makishima & the sybil system and the imaginary discussion between Makishima and Kougami. This is when the series said some of the most interesting things, it just never followed through with them in my opinion.
And my issue with Akane is
I'll admit that
Kanon is right that Akane and Saki's situations are different but I still feel unlike Akane I can see Saki's growth over the course of the series
whereas Akane just got tougher.
