The Episode where Skyler went behind Walt's back to accept what Walt felt was Charity from Gretchen and Eliot, was a pivitol point, up until then I feel Walt's focus was providing for his family feeling he was terminal, at first he wasn't Breaking Bad for himself at all, but after this, he became determined to do what he needed to cover his treatment, also when Tuco beat Jessy and stole his meth, Walt became Heisenberg blowing up Tucos HQ, from then on Walter's original motivations had transcended to building an empire even greater than Grey Matter.

Been a ST fan since the original series and beyond pun intended, but if Disney|Star Wars teaches us anything, you can make a new TV series starting from scratch (Mandelorian) they were brave enough to ditch lightsabers, jedi knights etc and simply by introducing a baby 'Yoda' like character they developed an all new universe to explore - Trekies are very loyal to the format even so, as these stories are all set in the future skip ahead a few light decades, man a new starship and Boldly Go where Noone has gone before seriously Parramount+ what's stopping you?
