I'll start this off with a disclaimer: I've only seen the two episodes that have aired so far. This is solely based off of those two episodes.
Normally, I would break this down into catagories and give detailed descriptions. However, I will simply give a brief overview of what I saw.
First, a heart-shape seems to be the recurring theme here. All the idols' eyes and hair have a heart shape in them when they catch the light. Personally, I find this to be corny and...well...stupid.
Second, I think this anime is another one of those magical-girl wannabe's that's disguised as a "friends are important, let's all sing" anime. Honestly, I think most people are going to hate it. I mean, it's so damn corny that I can't help but hate it.
Third, the sound quality and animation are it's only redeeming qualities. The insert songs are a little cliche but the CGI is well done, for the most part. If nothing else, at least they put the effort into the animation. I think, secretly, the artists wanted to make sure that at least SOMETHING good came out of it.
Fourth, I see no story here. I see a premise for a story...but no actual story. Again, this is only based off of two episodes so far but I don't really hold much hope for any kind of plot development.
This anime is like watching a train wreck: It's horrible and gruesome and it pains me to watch it but you can't help it once you start. Thank God there are only two episodes out right now or I would have put myself through hell finishing it.
Feel free to trash this little review if you want. As I've stated previsouly, this is only my opinion. I will finish watching it to the end and update as I need to. As usual, the overall score is an average of the 4 subscores.
UPDATE: After suffering through another four episodes, I can safely say that this series is not worth watching. The "story" is not well developed at all. This may be based on only watching six episodes but I can't see that it will improve at all. The fact that the animators saw fit to throw hearts into everything that catches a glare and the staff thought it would be a good idea to make this show as corny as humanly possible means that this show is suitable only for ignorant little children who don't know what real anime is.
