In my review I will be comparing Yozakura Quartet: Hana no Uta and it's predeccesor Yozakura Quartet.
At first I thought HnU was a continuation yet it was a reboot... kind of. The first that put me off of HnU was the moeization of characters. I need to say that I was literally scared of watching it because I would lost hope in Japan for making these... monsters. Not seeing the great not so quality rich DRRR-ish style animation was frightening but with different style animation came quality. I must say HnU is very well animated even though it doesn't seem as serious from first look as previous "version".
Story is a bit different, few characters changed their character traits and even alliances many new characters were added, presenting a richer enviroment. Unfortunatley since the reboot is a 2013 work, it's story features unimportant tropes as attending school and mostly fanservice. It was not even a minute of a first episode that I have been welcomed by catgirl's snow white underwear. There was a scene where they made licking certain someone's boob convinient to the development of the episode which made me (someone who hates fanservice where it does not belong) cringe.
Audio quality and variety can be really noticable when "shit goes down". There has been a new trend of using loud bass effects which I like to call ear rape. Mostly known in the part 3 of JJBA when Dio uses ZAWARUDO or most worth while youtube poops. I decided to actually praise it because it brings the feeling that everything is shaking or that it is strong/powerful.
It is certainly worth to watch but I would suggest watching both seasons as both of them have their ups and downs.
Yozakura Quartet was a bit of a dissapointment, Yozakura Quartet: Hoshi no Umi was insanely good and Yozakura Quartet: Hana no Uta falls in between the both of them. Yozakura Quartet gets treated as the ugly stepchild and that's pretty accurate.
So I realized halfway through the season that Yozakura Quartet: Hoshi no Umi should be watched halfway through the show, things will make a lot more sense and it all flows a lot better.
So I was really digging the art, the characters started to grow on me a lot more (even though I still feel that a lot of their 'uniforms' are kind of dumb) and I really appreciate the smooth and over the top animation style.
Compared to the first Yozakura Quartet series, this is all a lot more playful which feels more natural because you are watching kids. there is a lot more focus on comedic relief and it really works well with the characters.
Also the show knows the market they're aiming for so there are a few awkward panty shots, a bit of boob licking and quite a few inappropriate boob groping moments which wasn't somethat that really happened in Yozakura Quartet: Hoshi no Umi.
I think one of the stronger elements of the show is the lowkey romance development between Akina and Hime. Both went through a bit of a rework after Yozakura Quartet season and it really suits the show. It definitely adds a lot more cute moments. Hime and her scarf moments are put together extremely well.
I'll mention this again because I do feel it's important. Yozakura Quartet was a massive disappointment and Yozakura Quartet: Hoshi no Umi and Yozakura Quartet: Hana no Uta are much better viewing experiences.
In a town where humans and demons co-exist, it takes more than a normal police force to maintain the peace. Enter the Hiizumi Life Counseling Office, a fantastic foursome of unique teenagers, each gifted with an amazing super power!
Yozakura Quartet: Hana no Uta is not a continuation of 'Yozakura Quartet' but a complete new series with it's own story, the same characters are used with a few new additions.
I put that bit there because there's no synopses yet and at first I thought it was a second season, hope the info is useful to some.
about the show itself, I can't say much about the story yet because there are only 3 episodes so far, but the animations have definitely improved. they also made it less childish than 'Yozakura Quartet' and it feels much less rushed too.
the characters have improved too, in 'Yozakura Quartet' everyones personality was pretty mild but in Hana no Uta they are more anime-like with more extreme reactions.
all in all I like Hano no Uta much better and if it keeps up it'll be worth watching and much better than the first attempt from 2008.
