lol, compared to the first season the second two aren't nearly as bad. Let's see, blatant loli fan service at time (among ordinary fan service), child abuse in the form of a mother whipping her 9 year old child. More common nude loli transformation sequences.
A's had hardly any in comparison to the original series, centring more on the action, it had some but not nearly as much.
StrikerS is sort of the same, the transformation sequences happened once, injuries weren't that bad, fan service not as pedorific as the original series. Mostly centred on the action and gearing up to action (lol training).
