OP - It's good that they show a lot of the series's characters, but both the song and visuals were unimpressive. Fanservice was even more abundant here than Rosario+Vampire's OP...
ED - Like the OP, unimpressive. Lots of Lala service for Lala fans though...
-Why... must they try and make Lala's clothe transformations seems more erotic?
Has always found the manga decent, so it won't hurt to watch the anime, even if it won't provide anything above average.
The voices for all of the characters turned out very well, so I'm happy there.
Animation was decent, not too bad or too good.
Because of the way this manga/series is, I personally don't care if they follow the manga or not, since it really doesn't matter that much anyways.
For the first episode, basic average stuff, not much to say. Kept my attention, and way better than Rosario+Vampire could be in 100 years.
Preview: Reactions of schoolmates about Lala/engagement...
Oh, and my preference in both manga and anime is
Haruna>Lala
That's why I hope for Haruna x Rito. Though I wonder how far the anime plans to go...
