Psycho-Pass: Sinners of the System Case.1 - Tsumi to Bachi serves as a direct sequel to Psycho-Pass II having it's primary focus on Inspector Mika Shimotsuki and Enforcer Ginoza.
ACTUAL REVIEW :
Story : 6/10.
This story can be best described as a S2 story writing without any "disturbance" in plot by own allies.
Story Summary :(Potential Spoilers)
An unusual incident occurs - The case seems deeper than it is in surface - No direct cooperation from Sibyl system - introduction to the shady enemy hideout - threads become lose one after another as story progresses - A cool action scene - Dio-Jotaro moment - Villains dead - Case not closed - Oh It was ....'s plan all along.
Now I'm happy that the story writing did improve compared to S2 but paled in comparison to S1.
Art : 7/10.
A consistent art-animation as previous seasons. Never Doubt Production I.G.
Sound : 8/10.
Really good sound tracks, As long as they don't hamper the watching experience they don't bother me.
Character : 6/10.
The only major character with any form of significant development/progression is Inspector Mika Shimotsuki. Now, this is an hour long movie so expecting all major characters(who've already had a significant character moments in previous seasons and movies) is a bit too much. Inspector Mika Shimotsuki did grow-up on me,,just by a lil. bit and watching her in a scene wasn't as enraging as watching S2 and Psycho-Pass Movie and her progression as a character was a major highlight for me.
On the Other hand, the villains/antagonists of this movie were just bad, no form of evil presence was felt while watching them. Copy-paste a bad-character archeotype with a weird hiearchy and you'd get the antagonists of this movie.
Enjoyment : 8/10.
I love Psycho-Pass series. Regardless of the villains or plot, my attention is mainly toward Sibyl System and it's effect on the MCs and vice versa. Considering this movie as a prequel to S3, it served as a good watch.
Final Vedict : 7/10
This is just an hour long movie focusing on a case and it is fairly interesting as a stand-alone movie.And yeah,this story is a cannon.
If you just hate Inspector Mika Shimotsuki then you might not like this as the primary focus is on her. But watching this isn't a loss if you like Psycho-Pass series as it'll make easier to understand her character who's relevant in S3.
