Kimi ni todoke (Sparkly!!!)

Oh, I wasn't implying that. I was trying to answer your question. I've usually enjoyed whatever shoujo stuff I came across but they generally don't capture my interest if I'm say, browsing through a list of anime or manga. I would consider the sparkles and bubbles an unnecessary detail, but I accept that as a unique characteristic of this genre so it doesn't bother me at all. Sometimes, it's used to a nice effect though, in Kimi ni Todokefor example, I thought it helped show how Sawako sees Kazehaya, or Sawako's smile in the view of others.
