Can someone explain why Birds of Prey movie was well received?

I mean it’s certainly not good imo, but I’ve certainly seen worse. The Room, for example...

My buddy likes it a lot, and I realized I’m not so much critical of it as much as it’s just not my cup of tea; it’s far more of a Harley Quinn movie, which it’s adequate ti very good at, than a Birds fo Prey film, and it just really doesn’t feature an actual Cassandra Cain appearance, which to be honest was The only real thing compelling me to see it. I like other smaller scale superhero films better, but it’s not a bad movie; it’s just not one that interests me, and that’s not a bad thing.
