After squeezing 50 hours of stuff into two months and watching a 27-hour-long show in just under seven weeks, I'm not surprised I lost motivation to watch anything more...~
That lack of motivation seems to have impacted my enjoyment of what I've watched and read since, too... even with a mediocre show giving a bit back, it's still lacking...

Let's see if the show that might as well be heralded as the 'queen of cute girls doing cute things anime' (yes I just made that up) can return my motivation~

Music:
As a music anime, I look to the quality and quantity of the inserts as an important aspect.

But before that, before watching, my favourite song was actually the ending~ Because, well... I prefer proper rock to pop-rock~
Did my thoughts towards the ending change? No, it didn't~

The insert quantity is... very low. And with romantic lyrics and a soft-rock sound... they aren't particularly to my tastes, either.

As for the opening? Catchy and fun, but still not quite to my tastes...~

Characters:
Going into this, I prayed for not another generic, always bubbly, cheery and extroverted music protagonist. Though something told me Yui would be just like the others... this feeling from everything I knew about the show beforehand...

She quickly proved to have the 'immediately calling people by their first names' common to that archetype, but little else. Yet she still was a bit annoying. Maybe it's her voice? I don't know I'm not risking a music anime dub even if the protagonist's voice is annoying...~

Anyways, the next character I want to talk about is Tsumugi, the polite rich girl. She became my first favourite character, because of a scene where she was very cute and not at all slightly spookily deadpan cute~

Then Mio, a scaredy-cat, yet also quick to anger, especially when it comes to her childhood friend, Ritsu's, antics. She is another favourite of mine~
Her shy/embarrassed side is just so cute~

I personally find Ritsu a bit annoying, like Yui, but they're both still fun~ And I probably have a similarly low attention span...~

Then their supervisor Sawako... oh gosh she's silly~ A little weird, but like everyone she's funny~
And with a dark past, similar to many former Chuunibyous, revealed with such drama it adds to the comedy? Yeah, that gives her bonus points from me~

And introduced about half-way through, in episode 8, is the fifth member of the club, Azusa.
Serious, yet because of the show naturally she's still funny~ She's also a pseudo-cat-girl because... why not I guess?

Fun:
It is fun~ When the girls deflate, moreso when from pressure, the sound effects and animation make it so funny~

No matter if I've been frustrated day-long at my computer being slow or if the episode itself buffers every 5 seconds, I still end the episode smiling, having enjoyed it lots~
Even the beach episodes.

I decided to read the manga alongside it and... the anime expanded on a lot of it. The manga was mostly just the jokes, while the anime adds more character building and makes it more slice-of-life than just comedy.

Of course, bits that feel like shipbait do affect my enjoyment, but that is really subjective.

Overall:
While I feel like it's not the main reason I regained my motivation, it definitely helped.
Everyone's just always cute and/or funny and it's just so fun~
I am still giving it a serious, semi-thought-through score, though. Most of the lost points are for missing out on the opportunity to show a lot more cuteness, because it covers two years in only 13 episodes.
Granted there wasn't much cut from the manga – off the top of my head, just the group's friend on the student council ~~who I forgot to bring up earlier sorry Nodoka~~ prompting their performance at the start of their second year.

But still, the rating I give it makes it my second highest-rated, seriously-rated music anime~ I fully recommend it to relax after watching something heavy or to regain lost motivation~
