Uta no Prince-Sama follows this exact same format with the addition of the themes of idols, composers and music. Since something similar has already been done before with Kiniro no Corda, the writers seem to have tried to throw in some plot twists and other "mysteries", but unfortunately, as with most reverse harems, these are pretty predictable and hardly surprising.
Nevertheless, this show is far from being terrible or completely unenjoyable. In the reverse harem spectrum it's definitely somewhere in the middle, for it is neither a masterpiece like "Ouran Koukou Host Club" nor a complete abomination like "Diabolik Lovers". Rather, it stays in the mediocre-but-almost-good comfort zone with the likes of Kiniro no Corda, Fruits Basket, Vampire Knight, Bonjour Koiaji Pâtisserie, and many others.
Although the art is certainly much nicer than in the modern classics mentioned above, the animation could have used some improvement. Scenes involving singing and dancing often appear awkward or disjointed and would have greatly benefitted from more frames or even a little CGI. Additionally, the protagonist's eyes are a bit unattractive and disturbing to look at (although this is probably a matter of personal taste).
The music is perhaps one of the strongest points in this series, for it is fitting and enjoyable. While nothing out of this world, Mamoru Miyano does a great job at singing the opening as well as some other songs, and overall the seiyuus' work really shines.
Besides most seiyuus in this anime being well-known and award-winning, it was also refreshing to see (or hear) them do something different. Although I could tell that Mamoru Miyano would be in this series from the first episode, I actually had trouble identifying his character because he did not use the usual sugary sweet voice I've become accustomed to hearing in most eye-candy series in which he is featured. Additionally, Nakamura Yuuichi also voices a character that is completely different from his usual work, hence making things all the more interesting.
It is mainly thanks to the great performances from the voice actors as well as the lovely art from the animators that I was able to enjoy this series (which would have otherwise been an extremely generic reverse harem).
If you're a fan of (or are at least familiar with) this genre of anime and know what you're getting into, then this can definitely be an entertaining little show. If you have no interest in a bunch of mini-romances with generic subplots as well as pretty art and bubbly Jpop music, then you would probably be best advised to skip this.
