While Harley is the huge draw, the other female characters are generating buzz as well. I saw some cool Enchantress costumes (one that even had enough dangling stuff to make a jingly sound similar to the movie as the woman walked around) at the Edmonton Expo a week and a half back, and there were a few girls dressed as Katana as well. It will be interesting to see how this holds going forward with the lesser two characters.
WRT appeal, I think the fact that Harley appeals to females for the same reason that Deadpool does to males - both characters are strong but also get ahead by behaving bad.
Strong but imperfect and not impossible paragons of goodness and virtue like Wonder Woman, yep. I love Catwoman in Batman: The Animated Series and my heart pretty much just broke for Harley Quinn in the episode Mad Love. Rewatching Batman:TAS as an adult, I'm actually kinda amazed at some of the adult themes it contains. Why are a lot of modern cartoons so dumbed down?
Unfortunately, I wasn't able to watch Suicide Squad in theaters since I just had an operation (already bought tickets but ended up giving them to my mom) so I'll just have to wait for my 4K Blu-ray preorder from Amazon. , double-dipping this title and have the Best Buy steelbook preordered, too.
