I'm glad that this is not a sequel. The ending of the main series was already great the way it is.
I'll keep this review short to avoid any spoilers.
91 Days Special is mostly focused on the Vanetti family and how they rose into power, while the later part of the episode is focused on the interaction between Angelo Lagusa and Nero Vanetti. All these information contributes to the overall story of 91 Days; givings us an idea behind the characters' motivations.
So, should you watch this episode?
I'd definitely recommend watching it since it add details to the overall story. But of course, you can still
enjoy the main series even without watching this so the decision is up to you.
This is gonna be my first Anime review since i joined this site. And what a great way to start off by reviewing a special from 91 days, an anime that was my 2nd most favorite Anime of 2016 after Mob Psycho 100. I was so happy when i got the news that 91 Days was making a special and looked forward to it. And after seeing it, I was genuinely pleased.
The episode consists of 3 separate plot points. It more serves as a prequel of flashbacks with the first part (Shoal of Time) being at the time when the Vanetti kids were still
young, the second part (All our Yesterdays) which marks the introduction of Vincent Vanetti and his entry into the family, and the third part (Tomorrow, and Tomorrow) which catches up to the recent day right after the events of Episode 4 "Losing to Win, and What Comes After" with Angelo and Nero on the way back to Lawless.
Overall, the story is pretty good for this prequel episode. Although i enjoyed all 3 plot segments, the second segment where we first see Vincent Vanetti meet with Ganzo, Testa Lagusa, Orco and have an interesting game of cards together to pass time, really caught my interest a bit more. We finally get to see the more calculating side of Testa Lagusa, a character which had less backstory and screen time in the actual show. We also get to see a young ambitious Vincent Vanetti who joins the family and would later go on to be the established don of the Vanetti family in the main series.
*My ONLY complaint is the sequence of the segments. I feel it would've been so much more better had the first and second segments swapped places. The second segment should have been first in the episode since it was how it all began for the Vanetti family. It predates the first segment by a couple of years. Come to think of it, it's probably the very first event in the timeline of the entire show
If you are wondering whether this episode is important, then wonder no more: it does not contribute to the main plot in a major way...... but rather only in small doses. However, apart from some minor cameos, there are no teasers nor foreshadowing whatsoever. If you have seen 91 Days, then I do recommend you watch this just for the sake of a minor backstory in the form of a prequel flashback.
Would I recommend to watch it ? Definitely. That is, if you're a fan of the show. Will you have fun while watching it ? It depends on your expectations, but I'll say that it's worth spending your time.
I'm not much of a reviewer so I'll try to make this quick and simple.
This OVA is mostly focused on the past, showing us more of the Vanetti's background as well as Testa Lagusa's (Angelo's father) position in the family. It gives us some interesting info but it's nothing major enough to the point where you HAVE to watch this if you liked the first season.
The art was also quite lacking and I even found there to be some animation errors here and there along with some audio issues.
Overall, I'd say this OVA was disappointing. There wasn't much to it and I think it's
completely skippable. If you have other stuff you wanna do, I wouldn't put watching this at the top of your priority list.
