I don't trust that many modern writers would be able to address current affairs or history with any tact or subtlety. While morality was baked into the DNA of the original show, and frankly a huge part of it's appeal, given the current state of things I wonder how well that would translate to modern audiences.
In our day and age, morality, politics, religion, sexuality, gender, and so many hot button issues are all viewed through a subjective lens with far more ambiguity than in the past, so in order to work well as a story, the writers would have to be super competent to walk that line of bringing certain moral lessons to an audience without 1. offending anyone or 2. saying anything significant enough to be effective as a story. This is a huge part of my concern over the next Indiana Jones film. So much of how the past is portrayed is through modern sensibilities rather than being objective enough to remember that while we may have abandoned bad ideas in the present, in the past those very ideas were the norm. Whether for good or ill, if you whitewash history, you can totally mislead an audience.
