Has anyone else noticed the current anime op trend? Basically they (animators and animation companies) are now having fun messing arpund with background and space around the main characters. For instance, the Apochary Diaries op utilized blank spaces to help give a myseterious vibe. Undead Unluck, on tbe otherhand, utilizes constant background movement to show how bizarre the entire show is. Any other comments?
