I was an infant watching 80's Original Series movies - regularly mocked in the media for being films starring the "over the hill gang" and into The Next Generation where the Wesley Crusher identification figure for kids, was widely derided. Shows like Dawson's Creek and the O.C, even Roswell were actively avoided, despite them being my demographic. Buffy faired better, but more for horror trope, fantasy reasons than it being a show set in a school environment. I think sometimes the target audience don't watch TV showing them what their normal teen fashion, perfect hair, love and relationship trends should be like. They actually prefer to skip all that, be seen as not following a herd, wise beyond their years, and look forward to be treated like a real adult instead.
I don't necessarily see a Star Trek show focusing less on chasing a younger audience, as a bad thing. I mean, they're clearly trying too hard like that trendy teacher whose pop culture references and slang sound foreign, forced and unnatural. Be yourself Star Trek and you'll survive just fine. It's always a push to see where the boundaries are, a fall back position to something more traditional when that isn't as well-received and then a return to that when the audience eventually appreciates it. Academy's not going in the bin. Section 31 neither. Or Enterprise twenty-five years later. Nothing. It'll be an option right there to click play on forever more, prompting reaction love & hate until it's more positively reviewed. Their first episode,"Kids Like These" I liked well enough to press on instead of walking away. Section 31 was a bit of challenge to say anything positive about though and I'm somewhat glad they didn't follow it up.
