Good vs. evil and the importance of fighting for justice is highlighted here. So is looking sexy while doing it.
Guns are drawn (and, gasp!, even shot) in the Angels' pursuit of justice, but the action is very tame for modern times.
They may parade around in skimpy bikinis and miniskirts while solving crimes, but the Angels are as prim and proper as they come when it comes to romantic dalliances. They're rarely in serious romantic entanglements -- that is, anything serious enough for them to do more than kiss.
So clean it's almost laughable, given that the lead characters are supposed to be hard-boiled detectives.
