Canon and lore are sacred cows to many fans. Any deviation from the clearly established is met with scepticism and on occasions outrage. It is the hill they are prepared to die, defending. In the past I have felt equally as strong about this matter as others but over the years I have become increasingly relaxed about such things. I guess once you realise that your childhood memories cannot be ruined, despite what some claim, then you cease to worry as much. If you do not like an adaptation, extrapolation or continuation beyond the canon of a particular IP, then you simply say, “it’s not for me” and move on. Not liking an idea or concept because it doesn’t conform your preconceptions and personal tastes does not give you the right to try and quash it. So overall, I don’t mind Tom Cruise being Jack Reacher. A female Doctor Who is fine with me. I even like the movie adaptation of Raise the Titanic.
