***I blame the Ewoks.**
Especially those two horrid Ewok made-for-TV movies.
Then there is a disaster of some Christmas TV special from thirty five years ago.
You can find that Star Wars XMAS special on YouTube. I tried to watch it and it was terrible. Something about trying to get Chewie home to his family for XMAS. I am guessing there was some contract that compelled the cast to have to do this thing, but they are all in it.
