Well here are my thoughts on Princess Principal.
Plot (8/10) Tbh I found this to be the weakest aspect of the show. I'm not saying its bad but it's just not that interesting compared to the other aspects of the anime. The backstory of London being spilt into two parts, Albion taking control of the world, and the under-class rising up against the upper-class was very creative but I didn't really care for how it was executed.
Animation (9/10) While it's far from perfect, it's definitely gorgeous to no less. The fight scenes could have definitely been better animated but everything else like the background animation of vehicles, explosions, and buildings is definitely worth giving a hats off to.
Characters (9/10) My favorite character would have to be Ange, she's just to badass, imo she'd have to be the most well structured and well written character in the series. The other characters definitely had their spotlight and definitely had awesome moments of their own but Ange takes the fucking cake. Really liked the backstories of the
other characters as well. Dorothy's relationship with her dad is a bit sweet (despite her dads.....Disorder If you may call it that) and Beatrice's backstory was pretty sad as well. At the end of the day, all of the characters kick-ass but Ange is the best imo.
Soundtrack (10/10) Easily the best thing about this anime, the Soundtrack is absolutely stunning, there were times when I was watching and I just completely stopped giving a shit about what was happening and just completely gave into the masterfully composed soundtrack that has been provided by our Goddess Yuki Kajiura. I had nonstop eargasms all the way.
Overall Enjoyment (5/5)
I loved the Yuri moments, I loved characters, I loved the animation, I loved the soundtrack, the OP and ED were pretty good but nothing memorable, the story wasn't that good but everything else was awesome. This anime wasn't as good as Flip Flappers but I still had tons of fun watching it. I'll definitely watch it again possibly next month or so.
