Should I brake my oath

Breaking bad is one of my favourite series of all time. I can’t describe the feelings I get from it watching because it is very well crafted piece of work. But the ethical rule I follow is I don’t watch spin-offs of great movies or series cause I think in a way they are made to cash grab using the popularity of previous one . That is the reason I am holding back to watch better call Saul or el camino. For so long . But after listening to the good reviews of better call Saul . I am getting tempted to watch it . But I don’t want to ruin the purity of my breaking bad experience what should I do now guys
