I think they may have overestimated how much people liked her in Suicide Squad. I found her mostly annoying.
I dont think they under estimated that at all
I think Margot Robbies HQ was truly the only good thing about the movie and by far the most well liked thing about it
I think WB simply FAILED to capitalize on it and somehow managed to not only waste the potential for the character, But astonishingly HURT the character...
for me in comes down to a few disastrous and amateurish mistakes made by WB.
Theres NO EXCUSE for a potential Margot Robbie HQ movie to take 4 YEARS after Suicide Squad....that was simply way too much time, It seem any and all steam the character picked up from Suicide Squad was lost and completely forgotten, You have to strike while the Iron Is Hot....
The problem is, Like always with WB they had no Plan or vision for the Universe, character or movies...and after Margot Robbies HQ was so well liked in Suicide Squad, They had no idea what to do with her and had no plan or no one even in charge.....the sheer depths of WBs incompetence came be summed up here with this one astonishing fact....WB had 5 different "Harley Quinn" possible movies in development in the aftermath of Suicide Squad, lol They literally had A Joker/Harley movie in development, BOP, Gothams City Sirens, HQ solo movie, and Suicide Squad 2, they had absolutely no clue where to go with character and literally were just throwing anything at the walls to see what would stick.
Next Problem was, WB's stunningly somehow managed to ELIMINATE the very audience and fan-base that they needed for this film to succeed by going with a R rating...Harley Quinn's largest fan base are by far teenage girls between 12 and 15....WB's decision to make this an R rated film Literally Eliminated a large portion of the audience needed for it to succeed!
Next Problem, Inexcusably awful TITLE...This film was being sold on 1 THING "Harley fucking Quinn"....The decision to make the title Birds of Prey never should have gotten past the "Hey what If" stage....Harley Quinn and The Birds of Prey or something like that needed to be the title, Just a amateurish Mistake here!
Next Problem, Awful Production Problems and pre-release hype....The entire production process was an avalanche of Awful News that KILLED hype....from The news that Black Mask was gay and the plot involved him going after the BOP to get "Dick Pics" back to The constant new that Cathy Yan was in over head and WB was bringing in the directors of John Wick for reshoots....The entire Production process brought Nothing but Negativity to the movie
Last Problem, Its becoming clear now that WB has a Major Problem that they disastrously under estimated....
Its not as easy as Marvel Studios Makes it looks to take Unknown and Lesser Known characters and turned them into UBER successful franchises...
WB is know 0 for 2 with Shazam and BOP in trying to take B and C list characters and turned then into Movies and franchises that audiences care about..
for me the Key here, is WB disastrously under estimated the importance of a Cinematic Universe that spans 23 films over a decade which build a brand and audience that cares about every movie and every character(new and old)
WB saw Marvel Studios success Launching Unknown characters Like Ant-Man, Guardians of The Galaxy and even Doctor Strange and Black Panther....and Thought they could replicate that success
But Its pretty clear now, WB simply MISSED something HUGE....and That is, the key to turning Unknown characters movies into Instant Uber successful franchises is a Cinematic Universe that build a loyal fan base and cares about EVERY upcoming movie
WB just couldnt get audiences interested in these Unknown/Lesser Known characters.....
anyways thats my thoughts....
IMO Margot Robbie's HQ is just a massive missed and now DEAD opportunity for WB...
They had a character that was red hot coming off Suicide Squad featuring Literally the hottest A-list actress in Hollywood that easily should have resulted in a Trilogy of films making a minimum of 500 M+ each....
and instead, The potential franchise and character is dead after only 1 film and that 1 film is probably going to LOSE MONEY!
That is an unnecessarily long winded response to my post.
From my perspective, she was mainly popular as HQ because Margot is a stunning woman. Not really reason enough to give her a film of her own. You’re correct about them having missed the boat by waiting too long.
I don’t care much for Will Smith but found him to be the only character I liked in SS.
