The inherent problem with Dorn's idea is that the only people who would watch it or buy the DVDs of it are people who post on this forum. CBS knows they have to aim higher than that relatively tiny demographic, if they're even interested in producing a Trek series at all, which they aren't.
While I'm not a huge fan of the idea, I certainly think that an animated series would be the best way to go in terms of popularity and demographics (and I'm talking about animation on par with something like Macross Frontier, not something like that "Bob's Burgers" crap). However, setting it in the prime universe of TNG would be a mistake, for the same reason that Dorn's idea is a mistake. Abrams's Trek is what's hot now, so basing an animated series on that would be the smartest way to go.
