Well, I've been holding off on things Discovery until we started actually seeing some stuff, but I do declare the trailer is pretty exciting. It doesn't give a lot to go on, mind, but the promise of a more modern TV-style adventure featuring the full-on contemporary aesthetic and some good, solid donnybrooking with the Klingons is a winner for me, and I like what I see so far of the cast.
(I don't really care about the aesthetic matching the Cage, honestly. It would've been clever if they had managed that but it matters more for the aesthetic to match and look contemporary with the rest of current Trek, expecting them to paint inside the lines of Sixties design and effects budgets makes no sense. By the same token, I'd say leave the Cage alone. It's okay for it to be its own thing and of its own time, even if that exposes the fact that this is all just television.)
Anyway, as far as getting me genuinely excited for what's to come, yeah, this worked for me. Let's hope the actual show delivers.
