I did enjoy the anime, but after the second season it became a bit boring. There is not really a plot after the second season, as you know that all of the main characters are going to fall in love with the main protagonist, every single one of them. I mean the main group thats fine, but having Quartet Night and HE★VENS also wanting her, gets a bit boring and just leaves you hoping that it will actually end soon, or progresses with a plot.
I liked the art style of the anime and manga, its definitely one of my favorites.
I thought that the music from anime was amazing. I enjoy all of the opening soundtracks and most of the character songs. They are well thought out and appeal to a wide audience. Its a shame that most of the songs from season one have been taken off from youtube.
The characters are good but in this season, HE★VENS do copy ST☆RISH's characters a bit. for example; Nagi and Natsuki. They both have the cute and adorable personality, whilst one is rude and one has a split personality, which is also rude. Do you see where im coming from? But apart from the clashing of the personalitys, the characters have a really good back story.
Overall, i actually watch the anime for the music, tbh. The storyline does both me a little, but i put that behind me when new music is shown.
