And yet these are still all new characters.
Stop talking like you have all the answers. You haven't seen the show any more than the rest of us have.
Of course the characters are being changed, but it's nonsense to claim that makes them completely
new characters. As I already said, there's more than one single trait that defines a character. They're different versions
of the characters, with some things different and some things kept the same. Come on, surely you've seen this done before in things like Battlestar Galactica
or the different incarnations of Batman
over the decades, so stop talking as though you're completely ignorant of the principle. You should know better.
