1. Your examples of "Black Culture" just reflect the biases of the people who select examples of "Black Culture" for white people (and I'm pretty sure Hot Tub Time Machine, at least, is firmly a product of White Culture--did it have a single black writer?). I think you'd be better off looking at Blackish, Kendrick Lamar, Beyonce, and ahem Barack Obama.
2. When you set up an argument like this, I suggest you also explain why you think "Black Culture" is "broken." Because its easy to read what you've written as bottoming out in the claim that black people have created a broken culture. Why? Well there must be something wrong with black people! Lots of people do seem to make this argument (accidentally, of course--its often an attempt to make a racist attitude sound socially acceptable), and I doubt you'd want to be associated with them.
