But surely one can understand how a fanboy would feel sad about being told, for example, "The Solo children you know never existed."

Stargate SG-1 tells me that Ra was never the last of a humanoid race who built a network of stargates, but instead was one of billions of parasitic snakes who merely used a network of stargates built by a race of superhumans who became glowing jellyfish. I ignore that series and its spinoffs.

A Nightmare on Elm Street 4-6 and Freddy vs. Jason tell me that Freddy Krueger survived the events of A Nightmare on Elm Street 3 and killed off all the surviving kids from that movie, making Nancy Thompson's death totally meaningless. I ignore those sequels.

Highlander 2 revealed that Connor MacLeod and all the other Immortals from the first movie were aliens from the planet Zeist, Highlander 3 showed that Conner never actually won the Prize when he defeated the Kurgan at the end of the first film, and Highlander: Endgame had Conner die, losing his head to his own kinsman. I ignore each and every one of those movies.

Poltergeist II and III turn the primal, enigmatic Beast from the first movie into some goofy singing ghost preacher. I ignore both sequels.

Star Wars Episodes I, II, and III show that Anakin Skywalker was a murderous asshole, that Luke and Leia's mother was a selfish, racist airhead, that Obi-Wan was a senile old coot, that Palpatine was Henrietta from Evil Dead 2, that Yoda was a constipated frog on speed, and that the Jedi Order was made up of aloof, child-snatching, cultist enforcers. I definitely ignore those pieces of shit.

So, where am I going with all this? It's simple, really -- if someone fucks the canon up in such a way that pisses you off, then IGNORE IT and CREATE YOUR OWN. It's all fiction anyway -- no piece of it is anymore "real" than another.
