the most obvious one is the trend of gender swap (man character becomes a woman character , usually with a far more important role, to boost the character a bit) and racial swap (white becomes black) to get a perfect « diversity » in the cast of characters on screen which look totally artificial and very often derails the story from the original plot (because they absolutely want to demonstrate that woman are as strong as men, instead of just create a good plot). The only exception in my mind so far is « sandman ». Which also had the same swap, but the original writer being involved, he managed to do it in a much more intelligent way (turning lucifer into a woman, and death as a black character for example, are two very interesting choices, that other writers may have been scared to do).
