As much as I'm skeptical of Marvel, I think I like Netflix more because of its original (non super hero) content. While I get that Marvel movies are doing well and they want to sell as much a possible, I don't want Netflix to become all about this hero stuff, while more original stuff gets potentially ignored.
Besides that, its a great deal for Netflix, who many of the big studios do not want to succeed in their efforts. Take that Disney money and make more original stuff, Netflix. From the MD side of things, I think that Agents of Shield shows that on network tv, you can only go so far until timeslots, restrictions and moaning viewers/fans step in. Agents of Shield does look kinda cheap too. By doing these new series via Netflix, writers can go more creative and adult in content if they want(as these characters are kind of Marvel Knights ones. Only restrictions are money and imagination (and Marvel/continuity etc obviously.
Fingers crossed they turn out well, because I'm starting to worry that Marvel Disney is baking too many pies at once, and few will be tasteless and a waste.
