Star Trek was never seriously meant to be kids fare.
Oh, on many an occasion it lowered itself to that level, but truly, only geeky kids like myself (and those that post with me around here) ever really liked it.
What the current production crew is hoping for isn't going to happen...
More production money for the "Iron Man" and "Transformers" franchises, then. Cartoons and fan films for us.

You know, when something like "Star Trek" just doesn't change for four decades it de facto stops being entertainment for grownups because most of the grownups move on. Everyone's taste changes and evolves. Well, almost everyone.
Just because adults may watch an unambitious fantasy show doesn't make it challenging or intriguing entertainment on an adult level. Moore's "Battlestar Galactica" is adult science fiction, in 2009; the "Stargate" franchise is pitched at a childhood or adolescent mentality, regardless of the number of superannuated viewers.
