These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Uta No Princesama
Broken Base: For some fans of the original game the anime dumbifies the characters and loses the spirit of the original. However, there are also many fans who knew the franchise thanks to the animated series, and who prefer watching the guys interacting with each other than engaging in romance with Haruka.
Fridge Horror: Everyone's efforts to cure Syo's phobia of heights in Episode 5 may very well been making things worse considering he has a heart problem (not mentioned in the anime).
Ho Yay: Plenty. Couplings include Ren/Masato, Natsuki/Shou, Otoya/Tokiya etc.
Les Yay: Haruka gets REALLY happy when Tomochika visits her.
The Scrappy: Haruka, for fans of the anime. And Cecil for both game and anime fandoms.
