Not really, with how the story was structured and produced it was enjoyable to watch in its own context.
You haven't watched the movie? Harley does get majority of the screen time but all the supporting cast, including Black mask, get suitable character development and depth. Aside from the name Cain's character is excellent. Dinah gets the necessary screen time. They can add Barbara in the sequels or other movies, like the Bat films. They don't need to follow the comics entirely and they did good with the characters, especially Huntress and Black Canary.Yeah, even the reviews from professionals like Forbes don't bother to talk about them much. Even the supporters and WB uses Harley to attract ppl. How much screen time did Huntress even get and how bad was Cain butchered? Even Black Canary didn't have enough screen time as the founder of the team, which should have been the focus. And tell me HOW was Barbara given depth?
Comics take months to get produced, it's difficult to tell when they'll do changes like that with 100% accuracy since the industry involves hundreds of people. The movie is set to be a cult classic at the least. It's not as hated as the F4 movies were.Everything is pretty much settled. The only question is that does it have a tiny chance for the movie to break even. There will be no sequel and this version will be thrown into development hell much like the F4 movie.
