Great idea for a thread! I've such an ongoing yen to talk about this topic with no appropriate place to do so! In fact, I've had my Sif/Loki/Asgard idea in my sig for ages, and just last week I posted
this in the AC ratings thread when the topic came up:
I feel the same way, and I've mentioned this idea here or there. I, too, am really enjoying Agent Carter, so this isn't to say I don't want more of that show. But I think a different miniseries every winter would be a great way to explore supporting characters who would never get their own films. I've mentioned a "Tales of Asgard" mini with a Sif/Loki lead (Jamie Alexander is probably more likely than Hiddleston to get for more than just a cameo...) to bridge the gap between AoU and Thor: Ragnarok. If we get Brother Voodoo in Doctor Strange, a miniseries would be a cool way to flesh him out without making him seem redundant, or like a "black best friend," in Strange's film. The possibilities are endless.
Of course, one reason Agent Carter seems to fit so seamlessly into what ABC is doing is because of how closely it ties in to SHIELD. That would be sacrificed with some of my spin-off ideas. I really like your idea of keeping Agent Carter going, but putting some shows on a summer schedule (downside here being: isn't it harder to get good ratings over the summer? Viewership is down or something?)
So which Marvel TV shows would I like to see? Including the ones I stated above, and possibly others that have already been posted here:
1. Tales of Asgard (following Sif and/or Loki as the lead)
2. Brother Voodoo (if he's introduced in Doctor Strange)
3. Young Pym/Janet (don't rely on the special effects, rely on the story telling)
4. Maybe something villain focused, but I don't know what. AIM? The Leader? Folks have said Winter Soldier, but I more see him popping in the shadows across various properties...
I don't want to list too many, because I really envision these following the AC model, taking place in a AOS's downtime as miniseries. That limits us to one per year, and less if we get more seasons of AC. I would stick to focusing on supporting characters that had already been introduced, and keep it separate from the focus of the Netflix shows. What I mean by that is, let Netflix have the Marvel Knights style characters (a lot of people want Punisher, personally I would get behind a Taskmaster show, but keep those on Netflix). I just watched season 1 of "The Almighty Johnsons" on Netflix, which is about the Norse gods living in the guise of mortals in New Zealand. Even though the characters had limited superpowers, so to speak, the show really focused on telling the story, not displaying powers all the time. IF that idea were kept in mind, I don't think a period piece with Pym would be cost-prohibitive, but what do I know.
Again, great thread! I'll post more ideas if I get any.
) TV series similar to Gotham where James D'Arcy can reprise his role as an older Jarvis being a mentor to his young ward. The interplay between Tony (who would have to be very fast talking and quick-witted like RDJ) and Jarvis could be amusing.
