After Velma, I dunno how I feel about grown-up alternatives to Scooby Doo any more.
Maybe if we got a live-action or animated version of Scooby Doo that was more like Buffy the Vampire Slayer, and that half the time it's genuine supernatural phenomena then I'd be more interested.
Velma is an extreme example.
The series is too dumb for adult but too NSFW for kids.
I don't know who they're aiming.
I bet a new trailer will hit on March 10th.
Actually it's March 09, so your guess is really close.
