Luke Cage is all about Harlem, coming to terms with your past, community, and culture. It's also about street level superheroes and gang warfare.
Just as much as Jessica Jones or Daredevil, Luke Cage is about it's villains. They get at least equal screen time to the main hero cast of characters. This character development on both sides makes confrontations and payoffs feel like they have true weight.
Overall, Luke Cage has just made me even more excited for Iron Fist and The Defenders. I can't wait to see all these New York street heroes come together to form a rag-tag team. There are some nods to this in the story, especially with a recurring crossover character from the other Netflix MCU shows.
I still think Jessica Jones is the best season of TV Marvel has done but Luke Cage is easily above Season 1 of Daredevil. Personally, I would rank them from "worst" (worst in context but actually still good) to best Daredevil Season 1, Luke Cage, Daredevil Season 2, Jessica Jones. But that's just me. I can also easily see Luke Cage being someone's favorite out of this corner of the MCU.
As always, your mileage may vary, but I think it's definitely worth your time to give Luke Cage a shot.
