I like it. It's a nice theme. Sometimes I do skip it though.
Okay, just out of curiousity, but how many people here actually listen to the opening theme?
Personally, I find it to be the absolute worst part of an otherwise great show, but that's just my aversion to lyrics and intense amounts of sweetness talking.
Also I think they might be planning a new opening theme animation. One of the leaked screenshots that was released with the Luna Eclipsed screens showed what looked like a revised version of the current title animation.
