If you're wondering if GaruKura is worth the watch, it is! If you're asking yourself if you should watch this or the other Idol anime airing right now, the answer is watch both!
The animation is extremely good even if you dislike CGI, the characters are realistic enough that it's easy to relate to them, the music is great, there really isn't any reason for not watching this show.
There's an on-going issue right now with the subtitles being of a pretty low quality but once someone picks this anime up for translation please try to give it a watch and don't let it go under the radar, you wont regret it!
