With MOTU, people do feel like they have ownership of the story however, and I think those feelings are partially justified. MOTU has gone away for long periods of time, and the fans have had to keep the characters alive in their own heads. MOTU has never had a central storyline either, so we have been practically encouraged to come up with our own cannons. I heard this argument in terms of Star Wars. In the long span of time between trilogies, people wanted more stories, more time with the characters, so they wrote fan fiction, played stories out with their own toys, and watched the old material over and over and over, thus cementing the storyline in their heads. The thing with Star Wars is that Lucas cares about story (whether you think he is good at story is another debate). He has taken great pains to keep up continuity.
Mattel doesn't care about story or continunity. I applaud TG for trying to weave it all together. I don't like a lot of what he's come up with, but I really have been aching for a proper story arc for the brand. ANd since Mattel did such a bang up job with MOTU's overall story, it's no wonder TG's bios look a bit messy at times.
I just watched The People versus George Lucas the other day and recommend it. I think it has a lot to say about how this new comic series will be received by us fans, and god-forbit a movie is ever made. This quarrelling over story isn't unique to MOTU.
