Since this is the entry for the second cour of Tales of Zestiria, the majority of the people who disliked the first half already dropped it, so you are going to see more positive reviews than the show actually deserves. With that said, I will start a brief review of the entire adaptation:
Tales of Zestiria’s main issue is that it started airing in 2016. If you have seen a decent amount of fantasy anime, the "crew with different powers on a journey to save the world" premise gets boring quickly. As a baby's first show this probably does a decent job, but that doesn't
negate the fact of it lacking originality. When it comes to judge the directing, Zestiria is also disappointing. The original idea of taking some liberties with the plot seen in the game was interesting (since it is considered below average by a large portion of the Tales fanbase), but the outcome wasn't much better. There are various anticlimactic/awkward moments: like characters who laugh, cry or scream for no real reason. In addition, the slow pace of the first cour and the way they rushed the finale is not acceptable by any means, considering its length.
Ufotable provides high quality eye-candy, that's for sure. They deliver where other studios usually fail: smooth fights, good-looking backgrounds and CGI usage. That can be noticed easily by watching one or two episodes. On the other hand, this studio performed much better with older titles like Kara no Kyoukai or the Fate series. The character design is pretty, but part of the cast looked inexpressive or had forced reactions. It is worth mentioning that the CGI used with the dragons is not that good compared to other elements. Also, Zestiria is excessively pretentious when it comes to show off with the environment, and it feels like they wasted time that could have been used to fix inconsistencies with the pacing.
Music and voice acting: 6/10
Unlike other successful Ufotable works, Tales of Zestiria does not have a memorable OST. However, I felt like the soundtrack was acceptable overall, with FLOW taking the lead. The music used during the course of the show wasn't mold-breaking and is highly forgettable. Regarding the voice actors, most of them did a nice job, especially Fukuen Misato as Edna and Ono Daisuke as Dezel. Only a reduced amount of the characters did not have fitting voices.
Most of the cast is generic, shallow and has no real development. Rose and Dezel are two of the few exceptions, but they aren’t that great either. Besides, dealing with Sorey's dull personality is not an easy task if you have medium/high standards for main characters. It becomes a serious matter at some point of the story, where his mindset should change for the better, but he keeps acting the same way. Truly frustrating.
This show picked my interest after watching other works by the same team, and those expectations were slowly crushed on a weekly basis. I didn’t drop it hoping for a great fight scene that never came. Those two promotional Berseria episodes from the first cour were the most interesting ones, and that says a lot. At least the animation and OST made the experience slightly bearable.
In short, Tales of Zestiria is a walking cliché not worth the time investment. If you are interested in Ufotable’s gorgeous animation, Kara no Kyoukai and the Fate series are better choices. Most of the popular titles from the fantasy genre are also superior to Tales of Zestiria, and have done everything it does, but better.
