Ghost Rider requires too much CGI for Netflix so he can do with a reboot, 3rd times usually the charm. Moon Knight belongs on Netflix regardless. Blade can go either way, but I'd prefer he's on Netflix played by Michael Jai White, original choice was Michael B. Jordan, but he's in BP now so...yeah.
Personally I think they should do one big marvel horror R-Rated movie with a teamup against Mephisto and his army.
Ghost Rider, Werewolf By Knight, Blade, Man-Thing and an obligatory female character for good measure. All in a team up movie, and I think after the success of Deadpool, the public would eat it up. Maybe shove a little Marvel character cameo in there from Iron Man or someone alive and acive after IW and we got ourselves an MCU halloween hit.
You're thinking of Jennifer Kale and Satana. I approve of both.
And we do know that Man-Thing already exists in the MCU and was created by AIM since his ex-wife got killed in Iron Man 3 (assuming that she's actually dead since Extremis gave her a healing factor). I still am not sure if it's time yet for a Man-Thing reboot. And even then, would Man Thing be rebooted on TV or film side and if it's on TV, then how can Marvel afford his effects? If it's on film, then why give him priority over Eternals, Black Knight or Wonder Man?
The rumored Netflix series right now are Thunderbolts (who have too big of a lineup for a film, IMO), Blade, Ghost Rider and Moon Knight. If Marvel are to do yet another and slow down their production schedule further, I'd rather see it be Elektra over Man Thing since Elektra already exists, she has plenty of solo story arcs in the comics and she'd require a lower budget.
On ABC, Marvel didn't take the Mockingbird spin-off. Why would they take a show based on a rather atrocious film that was a box-office failure? They're allegedly doing a second half-hour sitcom and if you think that it's going to be anything other than She-Hulk when marvel have been working on a Hulk TV show and She-Hulk is the biggest sitcom property that Marvel have available to them. As for what'll air when Agent Carter used to? I have no idea but it might be. It might just be reruns or an original miniseries unrelated to Marvel.
On cable, it's less competitive than network TV but you need to look at what each channel caters to since they're all about niche marketing rather than general audiences. Freeform have a YA demographic that they're shooting for across all their programming. If they do a second Marvel show in addition to Cloak and Dagger, it'll probably be Runaways, New Warriors, Ms. Marvel or a show combining the casts of Young Avengers and Avengers Academy. Man-Thing is not a YA series. Man-Thing is a horror series aimed at adults. It wouldn't gel with everything else on Freeform.
On Disney Channel, I can see a Power Pack or Squirrel Girl series but Man-Thing? On Disney Channel? Besides the fact that you'd be putting a horror series on a channel directed at small children, it would also be a hard sell to have a character named Man-Thing with a phallic nose on the Disney Channel even if he were made cute and cuddly.
ESPN is the only remaining option and even then, I can't see them doing any Marvel series but NFL Superpro and even then that has a 99.999% chance of not ever happening. If it did happen, it would be late at night since basketball, baseball and hockey hog primetime and again, I would be incredibly shocked if Marvel would even pitch it. Why would Man-Thing ever happen on ESPN?
The ONLY place where I can see Man-Thing introduced to set him up for a team-up is another Hulk solo film which is dependent on the rights reverting from Universal. So please, don't mention Man-Thing again. He isn't going to happen.
