I read the whole manga. I've also read A LOT of Shoujo mangas. So with the score I gave it, I based it off of what I want in a manga.
The characters were not as likeable as I had hoped. I couldn't relate to them and I just couldn't bring myself to liking them no matter how I looked at them. I didn't care for the characters at all. Even with all that crying and acting I still didn't care. But I read all 35 chapters anyways.

The plot was really around acting and I only read it b/c of that. I'm familiar of mangas like that [Skip Beat!], but Penguin Revolution didn't live up to my expectations. There wasn't even any 'romance' per say, but there was just the tension of the beginning of a romance. I'm fine with that. I really don't care. But the different conflicts in the story were plain and simple, which is fine, but they were bland. Too bland. No spark or anything to actually make me want to reread a certain part or the whole series.

So yeah... 7 overall. I wouldn't recommend it, but it was still okay.
