The poster for season 3 looks pretty rad. I wonder if the show going down this darker/supernatural path might have something to do with the terror initiative they're trying to create over at Hulu with Marvel shows. Hellstorm interacted with Nico back in Avengers Undercover, so they could take some inspiration from that.
Also, this may or may not be relevant due to recent rumors about Marvel live-action productions being distanced from Marvel Television:
it looks like the cast was at the Marvel Studios office for some reason.
