I don't think there's any point in wishing for HT to take TV licenses on - and this is coming from someone who would prioritize TV characters over the majority of the movie stuff, (even the MCU stuff that I enjoy). They're pretty much going to be DC/Marvel/Star Wars from here on out, with something different here and there. You'd never get a decent run of any TV based stuff from them.
I would love to see more companies like ThreeZero, Star Ace, etc....to get more into the TV shows. I wish ThreeZero would get going with their Walking Dead line. I'm in for my favorites of the main characters.
I chose their Dead Space Isaac figure over Falcon or Star Lord, and I would choose Daryl Dixon in a heartbeat over any of the AOU figures (I'm only getting Cap, and that's 'cause I sold my only version of Cap).
Other shows I would love to see figures of: Fox's Sleepy Hollow (especially its version of the Headless Horseman), Supernatural (at least Dean, Sam and Castiel), Once Upon a Time (though this might be better served with a company like Tonner, because it's all about the female fairytale characters on that show anyway, IMO).
I wouldn't mind seeing some updated, superior versions of the main Buffy characters, as well as Mulder & Scully from X-Files, though the above are more of a priority to me. I still have my Sideshow versions of these characters. They're not up to today's standard, but I have so much nostalgia for those shows there's no way I would ever sell them without having something to replace them with.
Same with my Majestic Studios Dark Shadows figures. I would love for an updated version of Frid's Barnabas, but if I never get it my Majestic Studios figures will remain in my collection forever.
I ultimately get more attached to television characters than film ones, with some exceptions (MCU being one -but it plays like its own ongoing series so that's probably why it engages me so much), and I collect based on that, so I naturally tend to gravitate towards wanting more high end figures from my favorite television shows.
