Starmyu 3rd Season

I legitimately do not understand why or how this anime even managed to get a third season, especially so out of the blue. The first season was a pile of the most generic clichés and stereotypes, without even mortar to hold them together, about a few boys who had to learn to work together. The second season introduced more characters that had to learn to work together, so everyone had less screentime to help you even remember their names. And here's the third season, which... seems to add even more characters who have to learn to work together? Some of those are apparent upperclassmen, even, yet we've never heard of them despite all the time the original cast has already spent in the school?? And in all this time, neither the designs, nor the image or animation quality has gotten any better??? I simply fail to see any sort of justification for this, especially when there are countless others, at the worst as "good" as this, that get the axe after only one season, or two if they're lucky. The cast is just way too big, and holy smokes, there's maybe two or three of them that don't share the basic bland copy-paste look of everyone else - there are very good shots of them in episode 7, iirc, to showcase this, with the perfect bored look on all their faces to boot. Nevermind characterisation, just remembering their names is as close to mission impossible as it can get (there are character cards around the middle of each episode, sure, but even those are bad because the text is in the background that the characters just cover). They do a lot of running around (many times literally) to be able to perform together at the - wait, what even is that Ayanagi Festival, exactly? Frankly, if we ever got an explanation, I forgot, because it's that uninteresting to try to keep up with. And all this running around in 11 episodes, only for the thing to finally happen in episode 12... and then skydive into the post-credits scene, way beyond that, where they're not even just third years but even one step higher? Talk about pacing. Then the catchphrases add a layer of extra annoyance too: even with a big cast, one would be more than enough, especially if heard in every damn episode. Here we have three, and even a fourth has a cameo, because something has to trigger a completely out-of-place transformation. I'm not sure how this happened. I watched it because of a sort of principle: I've suffered through the first two, I might as well pick the third up as well. I'd rather like to avoid having to go for a fourth round though.
