How exactly is it non canon? Chances are they won't return to Endor but it was a big part of one of the movies. And so was Jar jar was Star Wars fans have to live with that. Something that I could see as non canonical would be Lifeday since it was something manufactured after the movies.
Also 5 stars. If the creators like the phrase "YouTube poop" then that's cool, kind of like "rock and roll." On one side you have Nickleback and on the other The Velvet Underground. So this is the VU of YTP.
I don't know from canon, but I know Ewok Adventures was better than the first two prequels (I never saw the third). At least in terms of writing and direction.
