The official release consists of two made-for-home-video movies (at least I know the second one was definitely made for video). By this I mean they were haphazardly put together by editing together episodes of the series to be feature length (kinda like the Young Indy series official release). The second 'movie' suffers most because there is no story arc, it really seems like a bunch of episodes without credits in between. Because of this there are many episodes left unreleased.

IMHO, the Ewoks cartoons aren't the greatest, but they're not bad either. I like some of the stories, and I do find it moderately entertaining. For me there is also a nostalgia element. Anyway, I do suggest giving them a view at some point.
