anjohl: You never have to accept ANY followup to a piece of media that you love as canonical. It's all fiction, you get to define your reality.
AndyBuzz: Well, that's all good and dandy, but keep in mind that the arts are mainly a form of communication between individuals. Isolating yourself from the rest, rips a very important part of the experience. Of course the specific examples you mention are shared and accepted by a large number of people (I for example agree on all four counts), so there are many cases where you are hardly alone. But in general you can not rely on the "ignore what doesn't suit you" proposition and still stay relevant with the specific work. The need and satisfaction to share the experience is there and sequels, reboots and remakes can ruin it -if their are done badly-, so getting angry about their mere existence is something that I find quite understandable.
Exactly. Before falling asleep, yesterday, I had been typing more or less the same thing :
I think it can be more awkward than some people assume. Fictionnal characters have an independant life, defined like collective myths. Luke Skywalker is largely defined, as a part of our modern mythology, as [SPOILERS] the son of Darth Vader. If you decide that Empire Strikes Back never existed, Luke Skywalker means something quite different for you, We can question if it's the same character, or only yours. In any way, you'd lose a common reference with the rest of the world. Isolated, it's not an important issue (we all do that), but it means you'll keeop bumping into occurences of, and references to, a Luke Skywalker, and a star wars background story, that is very far from yours. You lose the freedom of accessing freely to the shared, autonomous, outer, existence of these characters and story - which is, in my opinion, a nice aspect of public tales. If you make a habit of it, you can shut yourself into a weird bubble. Not all people wish to do that. Some are annoyed to see a "shared story" (after all, as a culture, we're partly tied by these shared stories) become something that separates us. Like when they made Bible 2, with [SPOILERS] the adventures of God Jr. and some mild retcon, some people decided to just blank it out and to stay with the original story, but doing so, they severed themselves from all the tie-in stuff that refer to both parts as a whole, and this lead to some awkward moments. Yet, of course, there can be situations of greater consensus, that make things more comfortable : many people agree that there was only 3 star wars, or only 3 indiana jones, only a couple of Jaws at best...
The stances in this thread are not mutually exclusive. I consider that Robocop is just one movie and that [SPOILERS] Lewis dies at the end, I consider that the James Bond series ended somewhere during Brosnan's run, I consider that Tolkien has never been adapted to cinema, that there are only two Terminator movies, etc. This doesn't mean that my position is quite as cosy as if it was technically true. When I'm exposed to Star Wars, it's most of times to stuff I don't relate to ("ooh, yes, star wars, coo... uh, why is boba fett everywhere ? what are we talking about, again ?"). When I hear of James Bond nowadays, it's to see some ramboïdal smerch henchman's mug everywhere. I can opush these aside, and I do, but I would have prefered a world where these concepts could be shared without second thought, or be offered to other people's discovery without having to specify "it's especially cool if, uh, you stop over there, but, well, for most people the story continues, and actually, this meaning here gets retroactively changed, and"...
You can block out some sequels, but having to do it is still an inconvenience. And whenever it happens to one more universe of yours, it's a valiud reason to sigh and roll eyes.
