even though the story kind of dragged in the middle, i think it recovered in the last episodes.
the show is a psychological thriller and since the start it makes you want to know what really happens in the group. it is interesting, suspenful and entertaining. some episodes weren't as good as others, i think the best episodes where the first six or so and the last two episodes, but i still think it is worth the watch, specially if you're into idol groups such as AKB48 and that sort of stuff. if you're into AKB48 you will find this group to be very familiar :)

i don't want to spoil anything, so i will just make a summary of why i liked this show: the thing i liked the most i that there is not good or bad characters, all of them are complex and you will find yourself very conflicted about their actions. there will be characters that you will think are likeable doing awful stuff and characters that may seem like awful people doing nice stuff, so it is pretty much like real life, there is no good or bad (in most of the cases) and i really appreciate that in a show. also, it gives you a glimpse of all the shitty stuff people in idols groups go through and all the stupid rules they have to follow in order to maintain this image of a perfect human being. there's no such thing as a perfect human being, and i think that's the moral of this story.

oh, and if you like anime or manga like madoka magica or magical girl site, you'll probably like this as well because there are cute girls with cute outfits but everything is fucked up.
