The Clone Wars
Be my guest and watch Spongebob. I never ever cared for that show and will ever ... But I'm not judging you for that honestly, but the fact is that many grown ups will not watch an animated show and it will not have the success for a long life ...
ran for five seasons and it wasn't eight-year olds who bought up all the DVD's and Blu-ray's.
Thing is, if you don't figure out a way to draw those kids in, Trek will wither and die as those of us who are fans grow old and pass away. Making a super-serious series solely targeted at adults is the surest way of killing Trek for good.
