Traditionally, most of Toei Animation's franchise follow-ups/spin-offs feature role reprisals from original voice actors, whether is the original Japanese version or the English-language dub (e.g. the "Dragon Ball Z/GT/Super" franchise). Unfortunately, the dub of "Powerpuff Girls Z" is a total departure from the original Powerpuff Girls show, its voice cast-wise.
Opinion changed from The 7D. I didn't like it, because it's often more bland despite the animation and the writing as well. It's kinda more like Teen Titans Go! I don't even blame on Parry Gripp's music.
