Hits Strong with the Intended Audience Birds of Prey is not trying to do what most MCU movies do and reach a broad audience. It's aimed at women who have been beaten down in life, whether by men in power, societal pressures, poverty, etc. To someone who hasn't experienced those things, characters may seem underdeveloped. But I didn't find this to be the case. The movie uses quite a bit of shorthand that many women will understand so that it doesn't need to spend too long on the backstories of five different women, and can instead jump into creating a dynamic between them. My favorite interactions were those between Harley and Cassandra, and those between Harley and Dinah.
That's not to say this is a perfect film. The first 20-30 minutes jump around in multiple different time-frames, and can be difficult to follow. Once it gets rolling in a chronological structure, this problem disappears, and it becomes a well-paced wild ride. Secondly, many people have pointed out that the movie focuses much more on Harley than it does on the Birds of Prey. This is 100% true. If you're coming to see a Harley Quinn movie (which to be fair, is largely how it was marketed) you will be very satisfied. If you wanted more of a Birds of Prey movie, you may be disappointed. Finally, I'm not well-versed in the comic book lore behind most of these characters, but as I understand it the movie takes a lot of liberties with them, and their movie counterparts are essentially different people. This could upset fans of the books who were hoping to see these characters represented on-screen.
However, if you're willing to look past these things (as I was) and you pick up on a lot of the subtext and implications, this is an incredible movie. In addition, the cinematography makes it a treat to the eyes. You could pause on almost any moment and have a great picture for your desktop. Finally, the action is fantastically choreographed, shot well, and the lighting makes it easy to see what's going on.
I highly recommend this movie.
