Take a moment to think about why anything is put on display to deliberately be seen and with the goal of entertaining.
A story that switches gender or race roles is automatically in comparison to it's original. Why? Cuz, other than those changes, it's a copy. If the original is great, we know why its copied, but it's not the original. No matter what, if the original is great, the copy almost always will be inferior.
So what, season 1 is the best cuz of writing and it happens to star 2 white actors, whom were stars at the time. We only care about entertainment, but dont be fooled with how theyre giving us more.
