Margot Robbie's Harley Quinn was the breakout star of "Suicide Squad" before the movie was even finished. Audiences were captivated by this insane villain with the high-wattage smile, baseball bat, fishnets, pigtails and a T-shirt that read "Daddy's Lil Monster."
But now that the film is out in theaters and being savaged by critics, that tide may be turning. Harley Quinn has become a divisive figure. To some, she's still the breakout. To others, she's the unwitting victim of a misogynistic story and an abusive relationship.
In the film, she's the kind of character who cackles gleefully after surviving a harrowing helicopter crash, and coyly asks "What?!" after changing into some skintight hot pants in front of dozens of men. She's also obsessively devoted to her boyfriend, the Joker (Jared Leto), who is also the one responsible for her transformation from accomplished psychotherapist to all out psychopath.
"It is a very difficult role," said director David Ayer. "You want to talk about a really, difficult, complex performance? Margot delivers."
Early on he got a tip from Warner Bros. that he should look at the rising Australian actress for the part. Ayer liked Robbie's ability to disappear into her roles and cast her in the film.
And they went to work crafting one of the more dysfunctional on-screen relationships this side of Sid and Nancy.
The character of Harley Quinn was introduced in the 1990s television show "Batman: The Animated Series," but soon the character seeped into the main DC comic books. While nowhere near as popular as, say Wonder Woman, she gained a sort of cult status. Filmmaker Kevin Smith even named his daughter after her.
In bringing the relationship to the screen, everyone was keenly aware of the potentially problematic nature of this unhinged couple. They had to strike a delicate balance.
Even Robbie has acknowledged her initial confusion about Harley's complete devotion to a man who treats her poorly.
"We wanted to make sure that she wasn't victimized and didn't come off being victimized," said producer Charles Roven.
Thus, they sought to make her the driver of her own actions. Producers also said they tried to make sure the Joker is as obsessed with her as she is with him.
In the movie, the Joker tortures her with electro shock therapy and gifts her to another man, while she fantasizes about suburban domesticity. In some versions of the comics, he regularly physically and emotionally abuses her.
Leto said that they pushed boundaries even more while shooting, but held back in the final edit.
"There's a lot that's not going to be on the screen ... (We) pushed the envelope quite a bit during filming. There are scenes that may never see the light of day between Harley and the Joker where we explored those other dysfunctional sides," Leto said.
Ayer's film needed to be PG-13, though.
"It's a very interesting time that we live in — a time where people are often crucified for mistakes. I can understand why people are very cautious about the decisions that they make," Leto said. "At the end of the day, the filmmakers and the studio have a film and they need to do what's best for the film."
Still, many critics, like Buzzfeed's Alison Willmore , MTV's Amy Nicholson and The Daily Beast's Jen Yamato , are dismayed that the relationship and the complex figure of Harley Quinn is not investigated further.
"What we see on screen is this ditzy blond who seems to be willing to do anything for this guy," said Alyssa Rosenberg, opinion writer for The Washington Post. "If that relationship's meant to be powerful and complex and ugly, it also needs to be complete. It deserves to breathe."
