I like easy reviews at times.

The cafe Cat's Eye is run by the Kisugi sisters who have double lives as a group of notorious art thieves hoping to steal back art work once belonging to their father who was a wartime art dealer which they hope would one day find him. Each steal more elaborate than the other helped by the fact that Hitomi is dating the detective in charge of catching them, they pull off each heist in their trademark cat suits.
As far as groundbreaking, this is likely the first largely dominant female cast in anime not under the magical girl or young girl genre, it's aesthetics were ground breaking for it's time as there really wasn't much sex appeal outside of Fujiko Mine and maybe one or two Go Nagai titles. What sells it higher is that all three women are very capable and it's a blast seeing them pull off each heist, sadly it's formula also means that if you've seen one episode there isn't really going to be many more that are different but I say it holds up better than most, just a pity Toshio is a complete dumb ass for not putting two and two together and not realizing the cafe and the thieves having the same name as well as both having three women are one in the same.
The original was never dubbed but the women all exist within the City Hunter universe and have made appearances in a dubbed OVA of City Hunter which I've not seen but I do recognise some of the cast so I'm not hopeful.
Final Verdict: Fomulaic but a fun trip through one of the stronger 80s animes of the time that really deserves more attention.
