I think it's just a different headspace for them conceptually to how they structure things.
I think that probably depends on the characterization and your opinion on Natalie Portman...To a degree we won't be. Or at least the character beats will be a little different; there's no Odin to bitch about, no Warriors Three to show up, Thor's worthy......but I'm sure she'll find other ways to be obnoxious.
I mean, to be honest I could see them making it a comedy bit of Jane trying to learn to wield Mjolnir and the hammer just dragging her around and she has no idea what she's doing.I'd like the same thing....but I don't think we're gonna get it. I think they're gonna want to move the story along, get to the punching, and use the "worthy" enchantment as an excuse to explain why she's so badass out of the gate; power *and skill* of Thor. Sadly, in this I expect the film to mirror the comics quite a bit. Might be one of the few places where the plots really align, but I doubt we get a "training montage" much less real screen time dedicated to Jane learning.
I think mini-sode stuff or animated prequels are probably more practical then OGN's, although Feige's practically in charge of everything now so he can do whatever he wants I guess.Yeah, and it keeps things from getting stale. Encourages people to watch each film too, so they don't miss stuff. But still. There's so much we never got to see. I'm telling ya, a OGN that actually got a little effort (unlike those bad prequel comics they do) would sell. Some of those DC OGN's have sold quite well, and with the marketing power of the MCU behind it, a "missing chapter" MCU OGN would put some damn solid money in the bank.
