The thing is that Shugo Chara Party is split in parts, a lot of cosplay, games, etc... Actually I think the idea is kinda original but the show has a lot of filling and it can be tedious, and yes, it is not what you are expecting of your favorite anime. Well, I don't think is overall wrong, I liked Shugo Chara Puchi , it sometimes was funny , the Rubik's Cube character game was cool, a character song is played so they could guess the character... and I liked the interview with the Amu's voice actor Even so I would have liked it was moreplot based, well, I liked the anime series, it was acceptable and enjoyable, Hikaru and Rika are adorable
I admit I've skipped a lot of filling to only watch the anime series part :p, but sometimes I watch them when I'm bored...
